Air Quality Detector
User Manual
Overview
The hand-held air quality detector can accurately detect indoor air quality. By adopting high-precision electrochemical formaldehyde sesor and American “TEMTOP” laser particle sensor and carbon dioxide sensor based on NDIR detection theory, it can transform the concentration of air pollutants to visualized data directly, providing air quality warning to protect the health of your family effectively.
Application
At home, cab or in public buildings etc.
Appearance
- Buzzer status: “
” indicates the buzzer is on. When measured polluant concentration exceeds the upper alarm limit, the buzzer beeps. “
” indicates the buzzer is off. When an alarm is triggered the buzzer will not beep. - Display the two states of the detector: Pause or measuring. “Measuring” indicates data is being detected. “Pause”indicates measurement pauses.

for 2 seconds to turn on/off the instrument. It can also be used to confirm certain operation. - Down or run/pause button: Press to decrease setting values or move down to select menu option. It can also be used to continue or suspend detection on the detection interface.
Notice
- The sensor adopts laser and NDIR (Non-Dispersive Infrared) detection theory, please keep the detector away from substances like fluff and hair to guarantee the accuracy of measured data.
- Please do not place the detector in an environment where particle concentration is more than 500ug/m3 and that of formaldehyde (HCHO) is over 1.0mg/m3 for long time. Long-time exposure to high-concentration air pollutants will damage the sensor and make it work improperly.
- Please do not bump, strike or drop the detector.
- Please do not cover the detection port or air outlet during use.
- Avoid contact with organic solvents which include silica gel and other adhesives, paintings, drugs, oil and high-concentration gases.
- Avoid using the detector in humid environment to ensure the accuracy of measured data.
