Co2 Air Detector Carbon Dioxide Detector Agricultural Production Greenhouse Co2 Monitor White Gas Detector Analysis Instrument

The CO2 measurement from 400 ppm and up can be a bit trigger happy. Sudanly it alarms with an anoying beeping sound, but the acutal CO2 amount in the room is not higher. What suddanly trigered it, can be some sunshine, moving the device, etc. I wish there would be an off button for the alarm sound. There is a temperature reading that tends to always display to high temperature. It might be 28 C inside the device, but the temperature in the room is no more then 23 C. There is a humidity reading that tends to always display to lo humidity. When there is 40 % humidity in the room, this display is showing 20 %. The price? Unbeatable!

Super fast shipping and excellent tracking right to the door. Exactly as described thank you. I've been using these for a couple of weeks and though they all have slightly different readings each one gives a consistent reading. I used a special glue in my art room and I thought it was moderately strong but it set the monitor off which bought my partner running...he told me that the smell was strong and opened the window. This alone tells me that it was money well spent.

My device was faulty, but seller is very honest and after discission and explanation of the problem we agreed on refund which I really received. I have usualy very bad experience in case when some problem occure on Adafar and I need to ask Adafar to step in, but now it was not a case. Despite I don't have working item, for me it is 5 star seller. Reliable seller, what's not usualy standard. Thank you and recommend seller to everyone.

so far the device seems to be working quite well and I'm sure it will give an accurate reading since its figures seem to fit within normal bounds of a household will see how it works with the fireplace going, ship fast Pack well highly recommended

Useless toy. Works only from charging (without charging works no more than 2 hours. Humidity sensor constantly shows 20% (that in the room that in the pool)

Inadmissible to pay high shipping costs and not to be delivered on time, the seller did not respond to my message.

Looks very nice, but i dont trust the values. Can be switched between Celsius and Fahrenheit.

The first opening is when did seem to fit the minutes or so after sought to bring! Perfect!

Perfect as described on the announcement arrived very quickly nothing to say well packaged
