UNI-T A25M PM2.5 Meter Air Quality Monitor Temperature Measuring LCD Backlight Celsius /Fahrenheit Unit Switching
Description:
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.
A25 series can be used in homes, laboratories, offices, hotels, schools, factories, conference rooms, airports, hospitals, restaurants, and many other public places.
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
