Description
A25M PM2.5 Meter
A25M (handheld) /A25D (benchtop) /A25F (benchtop) are air quality meters used to measure PM2.5 concentration. A25F can also measure formaldehyde concentration. PM2.5/Formaldehyde concentrations display different emoticons on screen to help users visualize their environmental conditions.
Key Features
1. Precise PM2.5 concentration based on pre-calibrated sensors
2. Temperature measurement (°C/°F)
3. Emoticon display
4. LCD backlight and red backlight alarm
5. Battery status, low power, auto power off
