Product Introduction 
The Moisture Meter operates on a resistance measurement principle. By contacting the paper surface with a flat round probe, it measures the resistance value of the paper and converts it into a moisture content percentage. The instrument has a built-in microprocessor that automatically performs temperature compensation and linear calibration, ensuring measurement accuracy under varying environmental temperatures. The LED digital display directly shows the moisture percentage without the need for charts or conversion tables. The flat round contact probe design allows easy contact with the paper surface, making it suitable for rapid moisture determination of various papers, paperboards, and corrugated boards. The device is powered by a 9V battery, requiring no external power source, truly enabling testing anytime, anywhere.

Main Technical Specifications 

FAQ 
1. What materials is the Moisture Meter suitable for?
It can measure the surface moisture of various papers, paperboards, and corrugated boxes. It is suitable for rapid on-site moisture testing in paper mills, box plants, packaging enterprises, and printing factories.
2. What should be noted when using the instrument?
Ensure the flat round contact probe makes good contact with the paper surface during measurement. Avoid measuring on surfaces with obvious stains or creases. The instrument uses a 9V battery; it is recommended to remove the battery when not in use for extended periods.
3. Does the instrument require calibration?
The instrument is factory-calibrated with a built-in automatic temperature compensation function that allows normal operation within an ambient temperature range of -5°C to +60°C. For precise calibration needs, contact our after-sales service or verify using standard moisture samples.

4. What if the displayed value is inaccurate?
First, check whether the battery is sufficiently charged and whether the probe is clean. If the problem persists, the instrument may need recalibration. Contact our after-sales service for assistance.
5. How is the battery replaced?
The instrument is powered by a 9V battery (6F22 type). When the display dims or goes blank, open the battery compartment cover and replace with a new battery. Replacement is simple and convenient.
6. Can the instrument measure internal moisture of paper?
This instrument is a surface contact moisture meter, primarily measuring the surface moisture of paper. For thick paperboard or corrugated board, surface moisture generally provides a good indication of the overall moisture condition.
