Description
TM-380 Multi IAQ Monitor
- CO2
- PM2.5
- PM10
- Temperature
- Humidity
Application
This meter can make 5 measures of air quality once a time, including CO2, PM2.5, PM10, temperature and humidity.
The measurement for CO2 is used for the air exchange rate of total heat exchangers or other ventilation fans or systems, the measurement for PM2.5 or PM10 is used for the cleaning capacity of air purifiers, and the measurement for temperature and humidity is used to estimate the dehumidification effect of dehumidifiers.
Features
- Real-time measurement of CO2/PM2.5/PM10/temperature/humidity.
- °C or °F unit selection.
- Locking function for Maximum value/minimum value/average value.
- Auto-shutdown function and disable auto-shutdown function.
- Adjustment and calibration function (CO2/temperature/humidity).
- CO2/PM2.5/PM10 red backlight alarm.
- Manual record and auto-record.
- Key sound assists to ensure the operation works.
