The MT28 Moisture Meter utilizes an electromagnetic field to penetrate a depth of ≤20mm. The hold function freezes the data, features a three-color display, and includes a sound alarm. Please keep a safe distance from metal objects while taking measurements. Press and hold the calibration button for at least 5 seconds. Auto off after 30 minutes, and a 9V battery is included.

The RDINSCOS MT28 Moisture Meter is designed for homeowners, contractors, and inspectors to quickly detect relative moisture levels caused by leaks and flooding, and measure the moisture content in building materials. Its key benefit is providing non-invasive readings up to 20mm deep using an electromagnetic field. A caveat to keep in mind is that accurate readings require maintaining a safe distance from metal objects during measurement.

Extended Product Information
FAQs
How does the pinless moisture meter work?
The MT28 uses an electromagnetic field that penetrates the surface up to 20mm to detect the presence of moisture. It measures relative moisture levels based on how this field is affected by water content in the material.
What is the 'Hold' function?
The 'Hold' function allows you to freeze the current measurement displayed on the screen. This is useful for recording readings accurately without the display changing as you move the device.
How do I know if the reading is high?
The MT28 features a three-color display (green for dry, yellow for moderate, red for wet) and an audible alarm that sounds when high moisture levels are detected.
How deep can this meter measure moisture?
The meter can detect moisture up to a depth of 20mm (approximately 0.78 inches) below the surface.
Does the meter come with a battery?
Yes, the RDINSCOS MT28 Moisture Meter includes a 9V battery.
What does 'relative moisture level' mean?
Relative moisture level indicates how moist a material is compared to a dry state, rather than an absolute percentage of water content. The three-color display helps interpret these relative levels.
Why should I keep a safe distance from metal objects?
Metal objects can interfere with the electromagnetic field used by the moisture meter, leading to inaccurate readings. Maintaining a safe distance ensures the measurement is focused on the material's moisture content.
Troubleshooting
Device does not turn on
Ensure a 9V battery is correctly installed and has sufficient charge. Check the battery contacts for corrosion.
Inconsistent or erratic readings
Ensure you are holding the device at a safe distance from metal objects. Recalibrate the device by holding the calibration button for 5 seconds. Ensure the surface being tested is clean and free of debris.
Display shows no reading or is always green
The area may be genuinely dry. Test the device on a known damp surface or recalibrate. Ensure the sensor pad is making good contact with the surface being tested.
Audible alarm is not working
Check if the device is muted (if applicable) or if the battery is low. If the battery is new and the device is not muted, the alarm may be malfunctioning.
Pros and Cons
Pros
Non-invasive surface scanning for quick assessments.
Clear visual and audible alerts for moisture detection.
Ability to hold readings for easy recording.
Automatic power-off feature to save battery.
Included 9V battery for immediate use.
Cons
Readings can be affected by nearby metal objects.
Requires user to press and hold a calibration button for initial setup.
Depth of measurement is limited to 20mm.
Relative moisture levels are indicated, not absolute percentage (unless calibrated).
Setup, Compatibility & Care
Setup:
Ensure a 9V battery is installed. The battery compartment is typically located on the back or side of the device.
Before the first use or after a long period of inactivity, it is recommended to calibrate the device. Press and hold the calibration button for at least 5 seconds until the device indicates calibration is complete (refer to the user manual for specific indicators).
Compatibility:
The MT28 is designed to measure moisture content in common building materials such as drywall, plaster, wood, and concrete.
It operates effectively on surfaces where relative moisture levels are a concern.
Care:
Keep the device clean by wiping it with a soft, dry cloth. Avoid using solvents or abrasive cleaners.
Store the meter in a dry environment when not in use.
Remove the battery if the device will be stored for an extended period.
Always maintain a safe distance from metal objects when taking measurements to prevent interference.
