Description

This air quality monitor (CO2 meter) has been tested as very reliable by the German consumer association and recommended as a recommended purchase.

High quality non-dispersive infrared (NDIR) gas sensor with CO2 measuring range up to 5000 ppm Ventilation advice based on CO2 concentration in the air. In addition, this unit also measures air humidity and temperature.

Ideal for public buildings such as hairdressers, schools, gyms, museums, sports clubs, etc. But also just a good way to measure the air quality at home.
Everyone knows how important good ventilation and air quality are. With this air quality monitor you will be warned to ventilate more if the quality of the air is not good enough. The quality can be read by the values ​​on the meter. In addition, you will receive ventilation advice because the color of the advice block changes.
(The numbers speak for themselves, the text on the meter is in German)

Before first use: 
The values ​​are displayed within 2,5 minutes. After that, it will (automatically) calibrate the device for another 24 hours to then display accurate readings. This process is repeated when you move the device, for example to measure the air quality in another room. This process enables the Technoline Air Quality Meter to guarantee accurate measurements.

Why do I need a CO2 meter?

Why should I buy a CO2 meter?

High CO2 levels in the air reduce people's concentration and performance, and it is easier for viruses to spread. Regular and timely ventilation is recommended to improve the indoor climate and maintain health!

Humans breathe in oxygen and exhale CO2. When many people are together in an enclosed space, there is less and less oxygen and more CO2 in the air. The amount of CO2 or parts per million (cubic meters) or PPM indicates how clean the air is.

The CO2 meter detects when you need to ventilate a room by showing the PPM that indicates how much CO2 is in the air.
If the PPM gets too high, the air becomes unhealthy and germs are more likely to be transferred. Viruses are easier to spread from 800ppm. In addition, if the CO2 value is higher than 1500ppm, it can already lead to drowsiness. As the ppm rises to 2000 ppm, people can experience headaches, poor concentration, loss of concentration, increased heart rate and mild nausea.

Room ventilation can reduce the ppm to a normal level below 800ppm

CO2 Levels and Guidelines

CO2 levels and guidelines

Below are some general CO2 reference levels:

400~600ppm
Background (normal) outside air level.

600~1.000ppm
Typical level for occupied spaces with good air circulation.

1.000~1.500ppm
Start ventilation of the room.

1.500~2.000ppm
Level associated with complaints of drowsiness and bad air.
Ventilation recommended!

2.000~5.000ppm
Level associated with headache, drowsiness and stagnant, stale, congested air. Poor concentration, loss of attention, increased heart rate and mild nausea can also occur. Ventilation highly recommended!

> 5.000 ppm
Exposure can lead to severe oxygen starvation, which can lead to permanent brain damage, coma and death. Requires immediate ventilation!

Nice shape, highly polished, 200ml, 5+ stars.
Size: 6.8oz/200ml Silver
Very nice, highly polished with the feel of quality for the price. I'm very much an amateur barista. A trip to Italy inspired me to buy an espresso machine. I gained a whole new respect for coffee in Europe. The pitcher with my machine was too big to copy the Euro style cafe. Small quantities of milk were too shallow to froth properly even when tilting. The barista I watched in Italy was using a small pitcher so I decided to buy the 200ml version. It's a perfect size allowing a small amount of milk to be deep enough to froth. I brought back some roasted Italian coffee beans back to USA and wow! I'm very much a beginner but having fun.

Still The Best Frother Ever!
Color: Black
I love how it is easy to use, how it holds a charge, and how much power it has. I've only charged it once since I got it & I've been using it on a daily basis!!! Though it isn't a long time, I'm happy with it so far! I definitely will recommend it to anyone looking for a great frother. If you are looking for one, look no further! You won't be disappointed! I've read some comments where they found it to be too strong that their drink spilled everywhere. But for me I have not had any incident of spilling over. I have used it both for my coffee and my matcha tea and it worked great without any spilling over. You just have to start with the lowest power and ensure that you have a large enough container to have a room for your frothing. My sister tried to use it recently during her visit to make us matcha tea. However, she experienced spillage all over the cup, because she had used a small cup. Otherwise, she liked it very much and said she will get one when her battery operated one stops working... Another thing I like about the product was the customer service that I had received. When I got my first order which came quickly, it wasn't working after having charged it over 24 hours. It was not turning on at all. I returned it and ordered a replacement which I received within a day or two. This time after charging it for the recommended amount of time, I was a bit skeptical when I turned it on. However, I was pleasantly surprised that it worked like it was supposed to and it has been working ever since having charged it only once so far. I may come back and give an update depending on how it does after 6 months of use, so keep in tune... I don't know if there is a way to write a new entry as a follow up to the old entry, so I'm going to add my follow up comment over here. May 23, 2025 - I love my frother more than I can say in words. It's functionality has not changed a bit from the time I have purchased it. It charge lasts several weeks to few months before I charge it again and the power is still the same. Recently I decided to buy another one for my office use. I like the white color and so tried it but that one wouldn't even turn on. And then I got a gray one to have a different color. That one was much weaker than the black one I own. Then I replaced it with another gray one within few days. I tried it and it was exactly the same as the one I already replaced. So then I decided to go with a black one again hoping that it would be the same as the one I have. The black one did much better than the gray ones in the strength or power of the frother. However, it is weaker than the one I already have been using since last August. While I am not very happy with the quality being inconsistent in all of the ones I have tried including the recent pictures of the black one, I have decided to keep the black one because it is relatively better than the gray ones I tried. What I don't understand is why there is inconsistency in the quality of the same product by the same maker. I am beginning to wonder if the black one I purchased in Augusta last year was anomaly of a quality and a good way. Maybe I lucked out on my older black frother, but I'm unsure if quality is going to get better if I were to order another one. I have a sister who is a pro in making coffee drinks and she was the reason I had ordered this frother to begin with. She uses a battery operated one at this time and I have been thinking about getting her one like mine. While I am still skeptical, I am going to give it a shot and order her one sometime soon. If it doesn't work, I guess we will return it back. But one thing that I am grateful is that I have been able to return every one of those that I have tried recently with no issues. I hope that I don't have to return my most recent purchase in black. I was not even able to review the new purchase because of the item being the same color which is crazy.

Outstanding Frother!
Color: Space Gray
Exceptional! This frother is in another league compared to the cheapo push button frothers. The motor is smooth, quiet and powerful. This has an intuitive thumb dial on top that operates smoothly with a wide range of smooth speed adjustment. It’s gentle enough to froth a little bit of milk for a macchiato and powerful enough to scramble 3 eggs. The head is removable for easy cleaning. It’s also rechargeable. I charged this the day I bought it on April first. I use it at least twice a day. It’s September 26th today and I have yet to recharge it and it’s not showing any signs of needing a charge. One minor quibble is that they give you 2 of the same frother heads. They are built so well, that I don’t imagine it ever wearing out. It would have been nice to get a whisk or something different. Not a deal breaker at all though.

Solid unit
Color: Black
Handheld Mixer/Frother Review A Premium Choice That Transforms Morning Coffee I am thoroughly impressed with this handheld mixer and frother. Each morning, I blend cacao and collagen powder into my coffee, and in the past, I always ended up with stubborn lumps using only a spoon or whisk. I had previously purchased a few inexpensive handheld mixers, but they disappointed me both in price and performance, struggling to mix the powders thoroughly—especially at the bottom of the cup. I came close to abandoning handheld mixers altogether, but decided to give it one last try. After reading countless reviews and carefully comparing models, I opted to invest in a higher-end handheld mixer. The anticipation was high—would this mixer truly distinguish itself from the budget options cluttering my kitchen drawer? From the moment I unboxed it, the difference was clear. The mixer felt substantial in my hand, and the build quality reflected thoughtful engineering. While this model cost roughly twice as much as the cheaper alternatives, it proved to be well worth the investment. Initially, I was concerned about the dial at the top, fearing it might be difficult to control. However, I was pleasantly surprised by its intuitive operation. The unit offers a solid feel, plenty of power, and a versatile range of speeds—from a gentle stir perfect for coffee to an impressively fast setting. I had not previously considered using this mixer as a frother, but as a cappuccino enthusiast, I decided to give it a try. I heated both 2% milk and oat milk to take the chill off, then submerged the mixing wand. Allowing the mixer to rise above the milk introduced air and created a rich, creamy foam—an unbelievable result. My homemade cappuccino now tastes like something from a café. The controls are robust, the construction is reliable, and the power is consistent. Cleanup is effortless, requiring only a quick rinse under the tap. The battery life is also noteworthy, lasting through several uses without losing strength. If you are hesitant to spend a bit more on a quality handheld mixer, I wholeheartedly recommend making the investment. This mixer has become an essential part of my morning routine. Excellent product—well done!
