Product introduction:
SRAT25M (handheld) / SRAT25D (bench top) / SRAT25F (bench top) 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. SRAT25 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 |
