Combined IAQ monitor, CO2, PM2.5, PM10, hygrometer and temperatu

Tenmars Taiwan combined IAQ air quality monitor, which can measure 5 air parameters simultaneously: CO2, PM2.5, PM10, temperature and humidity.
Application: CO2 measurement is important in evaluating the performance of indoor heat exchange and ventilation systems. PM2.5 or PM10 is used in the control of air purifiers, and temperature and humidity measurement is used to evaluate the dehumidification effect of dehumidifiers.
Functions:
Real-time measurement of CO2/PM2.5/PM10/temperature/humidity.
°C or °F unit selection.
Lock function for maximum value/minimum value/average value.
Auto-off function and disable auto-off function.
Adjustment and calibration function (CO2/temperature/humidity).
CO2/PM2.5/PM10 alarm with red backlight.
Manual recording and automatic recording.
When the measured value reaches the alarm setpoint, the LCD backlight turns red and the corresponding measuring elements flash.
Features:
Manual and automatic recording of values ​​up to 20 groups.
Automatic recording save interval setting: 5 seconds, 10 seconds, 5 minutes, 10 minutes, 20 minutes, 30 minutes, 60 minutes.
Sampling time: every 2.5 seconds (5 types, 0.5 seconds each).
Battery: Rechargeable lithium battery 3.7V 2000mAh
Charging: 5V micro USB interface
Display size: 52mm (L) x 40mm (W).
