FEATURES

- Key input (by pushing button) for selection of PM2.5 / PM1.0 / PM10 data display.

- Dust particle measuring range: 0 – 500 g/m3

- Detectable particle size: 0.3 - 10  m

- Accuracy (PM2.5): +/- 10% at 10 – 40 °C

- Resolution: 1 g/m3

- LCD display for measured dust particle concentration.

- Backlight for air quality indication

Green light represents good air quality. It will be on when the dust particle concentration is below 100 g/m3 .

Blue light represents moderate air quality. It will be on when the dust particle concentration is between 100 -150 g/m3 .

Red light represents poor air quality. It will be on when the dust particle concentration is above 150 g/m3 .

- +/- buttons: to adjust the clock, temperature unit (°C/°F), temperature offset (+/-3°C with resolution of 0.5 °C / +/-6°F with resolution of 1 °F), selection of PM2.5 / PM1.0 / PM10 data display by user. If no key is pressed for 10 seconds, it will automatically return to normal mode.

- Mode button: selection of clock / temperature plus air quality display.
