pH and TDS Meter Combo Include:
pH meter *1, TDS meter *1, pH calibration buffers *3, user manual *1
Various Applications:
The Mars Hydro pH and TDS meter combination can be widely used to test data in hydroponics, aquariums, drinking water, pools, and other liquids with quickly stabilized readings.
Accuracy and Measurement Range:
The measurement range of pH is (0 - 14), with an accuracy of 0.01. The TDS meter reads 3 different data with an accuracy of 2%, the measurement ranges are - TDS (0 - 9990 ppm), EC (0- 9990 μs/cm), and Temperature (0.1 - 80.0 ℃ or 32.0 - 176.0 ℉).
User-Friendly Features:
The lightweight body provides portability and the LCD screen provides backlighting so that users can easily read the numbers even in dark environments. Automatic temperature compensation ensures correct and accurate readings at different temperatures. "Hold" buttons on the pH and TDS meters lock readings for easy checking and recording. Both meters automatically turn off after 2 minutes of non-use to avoid battery waste.
4 Display Modes Of TDS:
The Mars Hydro TDS meter can read 3 different data (TDS, EC, Temperature) and switch between 4 display modes (TDS+Celsius, EC+Celsius, TDS+Fahrenheit, EC+Fahrenheit), so that growers can have easy access to the exact data they want.
Calibration of pH Meter
: Mars Hydro TDS & pH meter combo includes 3 pH calibration buffers to help growers calibrate the pH meter when it has been used too long or too often. Add the buffers separately to pure water, then insert the pH meter and press, then the pH meter will automatically calibrate itself. (Detailed tutorial in the user manual)
Notes:
*Avoid water or solutions above the immersion line when you use the meters.
*pH and TDS meter readings can be stabilized quickly within 5s, but it takes 3 to 5 minutes when reading TDS of pure water.
*Be sure to clean the meters with distilled water and put on the protective cap after finishing the operation.
*There is no need to calibrate the meters too often, as they are already calibrated before packaged.

Best bouncy bone!
Color: Orange/Large, Size: Orange, Color: Orange/Large, Size: Orange
My pups love these bones! They are soft and rubbery, but very durable. Had them for a little over 6 months and it has survived my extreme chewers and many tug of war games, and only has a few puncture marks! They bounce on my concrete floors and my pup loves to play fetch with this. Great purchase

Excellent for aggressive chewers
Color: Blue/Medium, Size: Blue
First I would like to say I think Jolly Pets are the best line of dog toys out there if you have an aggressive chewer. Their products have amazed me! And I am not being paid for this review. I have a 155 lb mastiff that is an excellent behaved boy but loves to destroy his toys. I had this bone in large and it held up excellent for about 4-5 months. I ordered it again in medium size by mistake and after 2 weeks it already has pieces missing...my fault. My only complaint is the medium size in blue smells like vanilla perfume. I can't wash it off. Although my handsome boy doesn't seem to mind. I just reordered in large. Also ordered a few other Jolly Pet toys as I am amazed at how they hold up. The "soccer ball" is my dogs favorite. It reinflates itself again and again no matter how much chewing or wear and tear its given. It's just magic!

This company makes great toys for pitts!!
Color: Blue/Medium, Size: Blue, Color: Blue/Medium, Size: Blue
Our pitt LOVES this toy. The rubber is reeeaally tough. It’s well designed because it’s a slippery surface. You can tell from the video there’s a lot of squeaking from him trying to get a good grip. He found a pretty good spot to hook his upper teeth into the crevasse, but his bottom teeth kept slipping.
As a side note, I wouldn’t leave any toy home alone with him that’s about 3 inches or smaller because dogs can choke on it, but that doesn’t make this any toy or company any less amazing. For toys I would leave home with a power chewer, take a look at that 4inch red ball made by this same company. He hasn’t made a dent in that thing and you can put treats in it. :)
