2. Główne cechy

• Digital, non-destructive pinless moisture meter.
• Optional plug-in wood probe; Optional plug-in Tramex Hygro-i relative humidity probe for relative humidity, temperature, dew point and mixing ratio readings.
• Deep signal penetration to over 1 inch into the materials being tested without the need to damage the surface; Signal penetration depends on the material being tested and meter setting.
• Specific gravity adjustment for most wood species.
• External Rubber electrodes make direct contact with the material being tested for best sensitivity and repeatability.

3. Konfiguracja

3.1 Instalacja baterii

The Tramex MRH3 meter requires one 9V battery (included). To install or replace the battery:

1. Znajdź pokrywę komory baterii znajdującą się z tyłu miernika.
2. Zdejmij pokrywę.
3. Włóż baterię 9V, zwracając uwagę na prawidłową biegunowość.
4. Załóż z powrotem pokrywę komory baterii.

3.2 Włączanie/wyłączanie

Press the power button (usually marked with a circle and vertical line) to turn the meter on. Press and hold the power button to turn it off.

3.3 Attaching Optional Probes

The MRH3 meter is compatible with various optional probes, such as pin-type electrodes and the Hygro-i2 relative humidity probe. These probes connect to the designated ports on the top or side of the meter. Ensure the connection is secure before use.

4.1 Non-Destructive Pinless Measurement

This mode allows for quick and non-invasive moisture readings by placing the meter directly on the surface of the material.

1. Turn on the MRH3 meter.
2. Select the appropriate material scale (e.g., "Drywall", "Masonry", "Laminate") using the mode selection buttons. Refer to the meter's display for the current scale.
3. Place the meter's rubber electrodes firmly against the surface of the material you wish to test.
4. Read the moisture level displayed on the screen. The reading indicates the relative moisture content within the material.

Note: Signal penetration depth varies based on the selected scale and material density.

4.2 Using Pin-Type Electrodes (Optional)

For precise moisture content readings in wood or other materials where penetration is acceptable:

1. Connect the pin-type electrode attachment to the MRH3 meter.
2. Select the "Wood" scale on the meter. You may need to adjust the specific gravity setting for the type of wood being tested.
3. Gently push the pins into the wood surface. Ensure good contact.
4. Odczytaj zawartość wilgoci w procentachtage wyświetlono.

4.3 Using Hygro-i2 Relative Humidity Probe (Optional)

The Hygro-i2 probe allows for ambient relative humidity, temperature, dew point, and mixing ratio measurements, as well as in-situ concrete RH testing.

1. Connect the Hygro-i2 probe to the MRH3 meter.
2. For ambient readings, hold the probe in the air in the desired location. The display will show RH%, Temperature, and Dew Point.
3. For in-situ concrete RH testing, follow ASTM F2170 standards. Drill a hole in the concrete, clean it, insert a sleeve, and then insert the Hygro-i2 probe into the sleeve. Allow sufficient time for equilibrium before taking a reading.

5. Konserwacja

5.1 Czyszczenie

Wipe the meter and probes with a clean, damp cloth. Do not use abrasive cleaners or immerse the meter in water.

5.2 Wymiana baterii

Replace the 9V battery when the low battery indicator appears on the display. Refer to Section 3.1 for battery installation instructions.

5.3 Przechowywanie

Store the meter in a cool, dry place away from direct sunlight and extreme temperatures. If storing for extended periods, remove the battery to prevent leakage.

5.4 Kalibracja

The Tramex MRH3 meter is factory calibrated. For optimal performance of the Hygro-i2 probe, periodic calibration checks using a certified salt solution are recommended. Refer to the Hygro-i2 probe's specific instructions for calibration procedures.
