Productbeschrijving

Met de Alecto COA3920 koolmonoxidemelder wordt je direct gewaarschuwd bij koolmonoxide (CO) detectie. De melder heeft een levensduur van wel 10 jaar. De melder is voorzien van een gestucte korrelige muurstructuur en valt daardoor onopvallend en mooi weg in bijna interieur.

Belangrijke eigenschappen

  • Snel en duidelijk inzicht via de meldingen in het display
  • De 10-jaars sensor zorgt ervoor dat je lang verzekert bent van een veilige melder.
  • De CO melder wordt geleverd inclusief 3 stuks AA batterijen zodat je direct aan de slag kunt.
  • De koolmonoxidemelder alarmeert bij te hoge concentratie koolmonoxide, maar waarschuwt ook al bij lage concentraties.
  • De koolmonoxidemelder geeft via display en via geluid en de lampjes duidelijk aan wat er aan de hand is. Bijvoorbeeld wanneer de batterijen bijna leeg zijn of de levensduur van de sensor na 10 jaar te einde komt.
  • Compleet geleverd met bodemplaat, schroeven en pluggen voor een eenvoudige en snelle montage.

Behuizing met wandstructuur

De behuizing van de koolmonoxidemelder, ook wel CO-melder genoemd, is opvallend onopvallend. De melder is namelijk voorzien van een gestucte korrelige wandstructuur. Zo valt deze in bijna iedere muur mooi weg. De CO-melder is compact (75 x 106 x 35 mm) en is geschikt om op te hangen, maar ook om neer te zetten.

Ook waarschuwing bij lagere concentratie koolmonoxide

Koolmonoxidemelders geven de concentratie koolmonoxide weer in ppm. Ppm staat voor parts per million, oftewel aantal deeltjes op 1 miljoen deeltjes. Wettelijk is het verplicht dat CO-melders alarm geven bij een gedetecteerde concentratie koolmonoxide vanaf 50 ppm gedurende 60 minuten. Ook wanneer je slaapt zal een alarm van >85dB niet onopgemerkt blijven.

Echter ook een langdurige aanwezigheid van een lagere concentratie CO is schadelijk voor de gezondheid. De Alecto COA3920 koolmonixidemelder geeft al een waarschuwing wanneer gedurende 60 minuten een concentratie van 30 ppm wordt gedetecteerd.

Extra inzicht via het display

Het display van de COA3920 biedt extra inzicht. Zo wordt de concentratie koolmonoxide in het display weergegeven, normaal gesproken 000ppm. Verder biedt het display inzicht in de batterijstatus en toont meldingen bij te hoge concentratie CO, test modus en eventuele foutmeldingen.

Hoogste kwaliteit

Zoals alle koolmonoxidemelders van Alecto zijn deze van de hoogste kwaliteit en voldoen ze aan de Europees Norm (EN50291-1:2018). De Alecto COA3920 heeft een testknop waarmee je periodiek eenvoudig test of de koolmonoxidemelder nog naar behoren werkt. Geen enkele zorg dus meer over koolmonoxide met deze handige CO-melder!

De Alecto COA3920 is ook verkrijgbaar in een uitvoering zonder display, model COA1910.

Gentle but Effective Cleaner
Scent: Tea Tree
This tea tree oil soap does an excellent job of cleaning without being harsh on the skin. It removes dirt and oil effectively, yet my skin never feels dry or tight after use. The lather is rich and smooth, and the light tea tree scent feels fresh and refreshing. Thanks to the shea butter, my skin feels soft and moisturized, making it great for daily use on face, body, and hands. A solid choice if you want a natural soap that’s both gentle and effective.

Don't Be Fooled By The Title On The Box🩷
Scent: Citrus
Let me simply say that I KNOW this soap is the "real deal". I am not one to give an average product an excellent rating. When I spend my money on a product, I write about the positive (if any) as well as the negative. Since being sick from 2015 to 2019, my skin tone changed from a medium "sienna" to having an unnatural ashy cast that that makes me always look ill although I am well ,now. When I looked at myself in the mirror in natural light, that "ashy cast" to my complexion didn't look healthy or attractive. I had come to accept that this would probably be an issue the rest of my life. I am a lady that never used foundation makeup but, decided to try it as a last resort. Using foundation makeup only made me look worse. I accidently came across this item while searching for another type of soap. When it arrived and I saw "Men's Soap Set" on the box 👀😩, I was devasted. I had ordered something that I never intended to order. I was about to return the item when I heard a clear message in my mind directing me to try the soap. Several months ago, I prayed and asked Our Creator and Lord to make my complexion healthy in appearance. That prayer came back to mind and I tried the soap without any further hesitation. I wasn't expecting anything but, to my surprise the soap immediately started removing that "ashy cast" from my face. Let me make it crystal clear that I had tried dozens of other soaps and products that did absolutely nothing to help. I have only used this soap once. As I write this review it is almost 7:00pm ET and I haven't turned the lights on inside of the house yet. I glanced at myself in the mirror and I can see myself and that healthy tone coming back. My prayer has been answered and I'm beginning to look healthy again! As for this soap, I couldn't ask for a better value for the money. This soap is of amazing quality. I will continue to use it. Don't be fooled by what's written on the box. This soap is for ladies as well. I can only speak about my personal experience but, it's a superior product in my opinion and definitely worth a try for anyone that has had an unnatural change in complexion. I give it five SUPER SIZED stars!!! 🩷🩷🩷

You'll be disappointed if you want pine scented soap.
Scent: Cedar
Has a mild scent, and not very pine like. I was disappointed. Grandpa's is still the best. I'm going to melt down the remaining three bars of this soap and add my own pine oil. The soap quality is good; long lasting bars that lather well.

A Noticeable Upgrade from Regular Soaps
Size: 3.5 Ounce (Pack of 6)
Leaves skin soft, smooth, and refreshed without dryness I’ve tried plenty of big retail soaps over the years, but this one stands out right away. The bar lathers nicely and leaves my skin feeling noticeably smoother and never dry, which is a huge improvement compared to what I used before. The scent is clean and subtle, not overpowering, so it works well for everyday use. I did expect the bar to be a little bigger, but it has held up better than I thought it would, making it worth the price—especially since I picked it up during a sale. Overall, this is a quality soap that feels more refined than the usual options, and I’ll definitely keep it in my rotation.
