About this item

• 【12in1 multi-funtional CO/CO2 detectors】With this 4in1 detector, we can detect the Carbon monoxide, carbon dioxide, temperature and humidity to keep us in a good air environment real time, Stay away from the harm of CO / CO2 gas poisoning.
• 【More accurated NDIR+electrochemistry sensors】NDIR+electrochemistry sensors combination, better to improve the gas detection accuracy. CO value range: 0~500PPM; CO2 value range: 400~5000PPM; Temperature range:32℉~122℉;Humidity range: 20~ 80%RH (±5%RH).

• 【Visible 3.7’’ HD screen & audible alarm design】All the gas data / temperature / humidity shows on the 3.7’’ HD screen real time. Green bar:0~99ppm; Yellow bar:100~149ppm; Red bar:150~500ppm. audible alarm sounds rapid “bi-bi-bi” when CO value exceed default 150ppm, default value can be custom-ed;audible alarm sounds slowly “bi-bi-bi”when CO2 value exceed default 15000ppm.
• 【Built-in 2400 mAh battery & backlight auto off design】Support 110+ hours long working time when charge full. Come with type-C cable, support working via charging. The screen will be backlight off after 10 min to extend the working time.
