Indoor Air Quality 9999ppm Digital Carbon Dioxide Temperature Humidity NDIR Sensor IAQ CO2 Monitor WB DP Tester

We have had to use this product two or three times since purchase and it has works exactly as advertised. Gave us readings and action to take accordingly. Easily portable which is nice as well. Don’t charge a battery in a closed space or leave a bucket of hot ashes in your house.

Compré el producto para medir CO2 de manera continua en el laboratorio, sin embargo no pude conseguir el software y cables adicionales.Tuve que comprar otro equipo de otra marca.

Compact seems to work well I've only used 3 times

Indispensable instrument in this time of pandemic to ensure that your environment is adequately ventilated. I’m glad I bought this; my tightly sealed house had a reading of 1600 PPM CO2 and this meter clearly shows when the windows have been opened long enough to bring CO2 down to a healthier level of 600 to 800 ppm.Buy this if you want to look like a contractor. It’s ginormous and yelliw but actually light weight, especially for the size. C02 reading comes up in 30 seconds after a countdown; initial indoor relative humidity indoors after unit is outdoors takes a while to stabilize maybe ten or 15 minutes.The toggle between air, wet bulb, and dew point temperature is nice; kind of wish it also showed heat index.Now the bad: Terrible human factors design; without the manual you’d never figure this thing out - fortunately the tiny manual explains it all pretty well. Don’t lose the manual. Buttons are excessively debounced to the point that sometimes a button press isn’t recognized. A RS232 interface??? Stone age technology and forget about using your phone to log data.Alarm initially set to 1000 PPM probably isn’t a good choice; if you take this to your local grocery store or neighborhood bar or school or workplace and make a measurement that’s above this strict limit you’ll freak everyone out. It’s easily changed (but don’t forget the manual)I would buy this again. It works well. I like it.

とにかく、値段の変動があり過ぎる二酸化炭素測定器全般。この商品の最安値価格は、15000円台でしたので、その前後の価格での購入をお勧め致します。色が微妙な所が微妙なのと、もう少し小型ならとも思います。性能自体は問題なく優秀です。
