Multifunctional 5In1 Co2 Meter Digital Temperature Humidity Tester Carbon Dioxide Tvoc Hcho Detector Air Quality Monitor

I received the Air Detector product in very good condition by courier (Meest - Poland and FanCourier Expres - Romania) and not by Romanian Post and I tested it. It works in normal parameters and shows the temperature and humidity like other appliances in the room (weather station, clock with thermometer, etc.) A quality seller and very serious so thank you very much! All indicated data are analyzed and played randomly depending on the air entering and leaving the unit.

kind a useless. in fact it is 3 sensors and temp and moisture all the time in home, showing minium values only when you exhale near it it ring alarm and shows a lot co2 if you do same with cigarette smoke shows bigger values on pm2.5 (pm10 is most dangerous and this sensor not have it) its more usefull as fire detector. bcs of co2 and pm values.

Three of the city of pusalka were not delivered to the city, in the package of pupyrkoyu, ale ce did not vryatkuya. The salesman did not help Z 'yasuvati, so the track number was mixed! Those shchos are small from the entrance to the new rock, with 3 spare parts on two-half-city and half-town.

It is as shown in the description. Looking good. I am very happy this says me my environment is green status. One thing is needed. screen saving mode should be selected by user when it is needed. I am afraid it will burn the screen for the long time operation.

All right, I like it to carry Type-C connector, plus instructions in Spanish, if I like to laugh that the battery lasts a little longer, it's very light, it shows in real time the amount of CO2 that may be in a room, relative humidity and temperature.

The device is normal, something shows, it's difficult to judge. Testimony from the race is quite strong, but in principle the performance can be obtained. The battery holds about a day, there are two wires in the kit, there is no charging.

Weather because the colder in LCD for initial start-up dark beauty indoor temperature in car 츰 OK Centipede to operating condition good How well fit the image. Tea box within the vehicle air pollution degree check 꼄 buy together.

I compared with several other Tester, a fluctuating difference of 1% CO2 was found. Too bad that the measured temperature rises to 28 ° when charging. Otherwise I recommend this tester that very precise.

Temperature and humidity incorrect. The rest I have no how to tell but Skoro simplest functions work wrong this rest will be even worse. Not worth.
