Indoor Air Quality Monitor Testing for PM2.5 PM10 Formaldehyde TVOC, with Date Time Temperature Humidity,Multifunctional Air Pollution Detector(without rechargeable battery)

Description

This air quality monitor for multi-function board,built-in high-speed 4 nuclear 64 - bit processors, used high precision sensors,adopts world-advanced processing technology.This monitor for civilian products do not compared with specialized experimental instrument. This monitor can detect: temperature, humidity, HCHO, TVOC, PM2.5, PM10, toluene and other harmful chemical volatiles and pollutantin the air, carbon monoxide, smoke,fog, dust, alcohol, glue, paint, ink,such as perfume, all have good detection effect. Power supply: The product without rechargeable battery,needs to connect plug and keep charging all the time. If you need to move to other places to measure, you can use a power bank to supply. Product function parameters:PM2.5: 0-500ug/m3; Precision: 1 ug/m3PM10: 0-999 ug/m3; Precision: 1 ug/m3HCHO: 0-99.99 mg/m3; Precision: 0.001 mg/m3TVOC: 0-99.99 mg/m3; Precision: 0.001 mg/m3Temperature range: -15-50°CHumidity: 15-90%HR Package including: 1 * Air quality monitor 1 * USB line 1 * English user's manualKey signs or symptoms maybe associated with bad air: Conjunctival irritation, nose and throat discomfort, headache, allergic skin reaction, dyspnea, declines in serum cholinesterase levels, nausea, emesis, epistaxis, fatigue, dizziness and so on.Tips: After using this detector boot need 120 seconds is timing monitor preheating process, users need to be patient. Preheating is limited to HCHO/TVOC sensor. After the first use the boot after 120 seconds preheating,such as testing data on the high side,floating up and down,0.000 or 000 belongs to the normal,please move the monitor to the air flow is benefit or air quality good place 1-3 hours, monitor returned to normal after safety data is used,also can be manual calibration instrument or instrument data reset after use.
