IAQ Formaldehyde (HCHO) Logger

INSTRUCTION

SHEET

FEATURES

1) Super large LCD simultaneously display of HCHO level, Temp., Relative humidity, Calendar (Y/M/D) andTime (clock).

2) Three (3) smiley icons indicate indoor air quality levels (0/0.08/0.8ppm), easy to understand HCHO concentration.

3) Stable Electrochemical type sensor for HCHO detection.

4) High alarm threshold is selectable.

5) Manual 0ppm calibration.

6) Audible/Visible LED warning for high HCHO concentration

MAINTENANCE

Cleaning and storage:

1). The meter should be cleaned with a damp cloth and mild detergent when necessary.

2). Store the meter in an area with moderate temperature and humidity.

MANUAL CALIBRATION TO ZERO

Before start HCHO manual calibration make sure the area is ventilation and no HCHO environment. Ensure the calibration completed, to use adaptor during calibration is recommended.

HCHO meter is completed calibration in factory before

packed. Manual calibration is only for meter inaccuracy.

When power on, long press button moreUNIT than 6 seconds, the value will turn into “00000" and flash seconds.60

After calibration completed, display will show full LCD icon for a second. Meter will restart automatically to return normal measurement.

BATTERY INDICATION

When battery is low (HCHO consumes power ),the reading of HCHO will be terribly high, could be couple thousand in ppm. “LO BAT” is flashing at the bottom of the screen, near calendar and time. Replace new battery when LO BAT shows.

SETTING DATE & TIME

since powered on.

3)STEL: (Short-Term Exposure Limit in 15 minutes weighted

average)The meter keeps updating readings every minute. If the meter has been powered on for less than 15 minutes, the STEL value shows the weighted average of reading taken since powered on.
