1. Introduction
This is the NON-Contact Moisture Meter, an electronic dampness indicator with a measuring process working on the principle of high frequency. The instrument is used for non-destructively tracing dampness in building materials of all kinds, as well as for detecting damp distribution in walls, ceilings, and floors. It is particularly suitable for pre-testing the readiness of building materials for covering prior to CM measurement.
2. Features
- Quickly indicate the moisture content of materials
- CM % measured function
- Depth of penetration about 20-40mm
- Measure and HOLD Function
- MAX/MIN display Function
- Alarm Function
- Low battery indication
- Auto Power Off
- White Backlighting LCD Display

The LCD Display shows various indicators:
- [HOLD symbol] - Data Hold indicator
- [DRY symbol] - Dry status indicator
- [RISK symbol] - Risk status indicator
- [WET symbol] - Wet status indicator
- [MAX symbol] - Maximum value indicator
- [MIN symbol] - Minimum value indicator
- Numerical display for current moisture value, MAX value, and MIN value.
- [low battery symbol] - Indicates when the battery needs replacement.
5. Operation
To turn the meter ON, press the [ON/OFF Button]. Press the [MEAS Button] to start measuring. For the first measurement when the meter is turned on, hold the meter up so that the ball sensor is in the air, not covered by your hand or any surface or object, at a distance of 8 to 10cm. The LCD will display "CAL" indication, followed by the moisture value. This value must be below 0.5. If not, turn the meter on again and repeat the calibration operation. The meter will then start measuring the object.
Press the [MEAS Button] again to latch the moisture measurement on the display. The [HOLD symbol] will be displayed. After 30 seconds, the meter will automatically turn off.
Note: Calibrate the meter once when you turn it on. If you move the meter from one place to another, recalibrate it.
6. Alarm Set Mode
Press the [ALARM SET Button] to enter the alarm set mode when the meter is in data hold mode. The "[RISK symbol]" icon will appear on the LCD. Use the [UP Button] and [DOWN Button] to adjust the threshold. Press the [ALARM SET Button] to save the alarm setting. Then, the "[WET symbol]" icon will appear on the LCD. Use the [UP Button] and [DOWN Button] to adjust the threshold. Press the [ALARM SET Button] to save the alarm setting. The meter will then return to data hold mode.
If the moisture measurement is higher than the RISK alarm setting, it will beep once every 2 seconds. If the moisture measurement exceeds the WET alarm setting, it will beep four times every 1 second.
Note: The RISK value can be adjusted from 0 to 50 (default value is 30). The WET value can be adjusted from 50 to 100 (default value is 60).
7. Backlighting
Press the [UP Button] to switch the backlighting on or off when the meter is in the data hold mode. The displayed screen will be backlit with a series of white LEDs.
Moisture Table of Comparison
| Construction Material | Display (Unit) | Moisture Status |
|---|---|---|
| Gypsum | <30 | DRY |
| 30-60 | RISK | |
| >60 | WET | |
| Cement | <25 | DRY |
| 25-50 | RISK | |
| >50 | WET | |
| Wood | <50 | DRY |
| 50-80 | RISK | |
| >80 | WET |
Notes
- If measuring near corners, maintain a minimum distance of 8 to 10cm from the corner area.
- The ball head must be kept perpendicular to the measured material during measurement, pressed firmly against the surface and not slanted.
- In the case of material thicknesses less than 20cm, there is a danger that moisture values may not be correct.
- If "BAT" appears in the display, the battery should be replaced.
