Co2 Meter Co2 Detector Multifunctional Thermohygrometer Home Gas Household Digital Air Pollution Monitor

The sensor works like a fire alarm. If there is a lot of carbon dioxide in the room, a short signal is triggered. After that, the number does not fall down any more, even if you take it outside. We have to stop the device. On the battery works only 2 hours. I do not advise buying. The device performs normally only the function of temperature and humidity.

Good, clear readout. Case feels substantial and strong. Just two things to know that aren't in the description: 1) the colour bar flashes to indicate the CO2 range. This might be distracting. 2) the unit doesn't seem to charge while it's switched on. I tried charging while running for 48 hours and it remained uncharged throughout that time.

Rules for its price. Cons: -Lying (overstated) temperature -And humidity, like, lowers -Sometimes tupit, dramatically improves the PPM to critical. Treated by reboot. If the price was high, put below. And low-cost not the precision instruments, go.

In Kiev, the sensor was delivered for 3 weeks. The goods are in excellent condition. The readings of humidity and temperature sensors vary slightly with the readings of my home sensors. Seller recommend.

Arrived a little late but very well Packed, well protected. The leaflet is in several languages including French very appreciable. I put him in charge. I will come back if need to finish the notice.

I am very satisfied, but it is necessary to leave the appreil connected because the battery is empty very quickly.

According to my feelings, these are correct. Numbers can swim a little more a little less. Thats ok.

Fully ventilated high product quality also great hand slants cold to give a dish with ㅎ ㅎ
