Moisture Meter Pinless (MO280) Non-invasive to 3/4" Depth

Product details (archived)

The information below is retained for reference only. This item is discontinued and cannot be ordered.

The square sensor on the rear of the instrument sends and receives a low power electromagnetic signal through the material under test. The LCD
shows the average moisture content (in %) of the material under test to a max. depth of ¾” (20mm). Moisture that is closer to the surface of the
material under test has a greater effect on the average than moisture deeper in the material. The MO280 is an auto-calibration device; no user
calibration is needed.

Features:

• Select from 10 wood types and measurement ranges
• Measurement depth to 0.75" (22mm) below the surface
• LCD displays % moisture of wood or material being tested
• Quickly indicates the moisture content of materials
• Select from 10 wood types and measurement ranges
• Automatic internal test and calibration
• Electro-magnetic testing technology
• Low battery indication

Directions:

1. Slide the rear power switch to the ON position
2. IMPORTANT: Hold the meter up so that the rear sensor is not covered by your hand or any surface or object. If the meter emits chirping tones, the sensor is entirely or partially covered
3. Momentarily press the MEASURE button to activate the sensor (the LCD display will switch on)
4. Press and hold the UP or DOWN button to select a material group 0 to 9 (see table below). When the desired group is displayed, release the button. The meter will briefly chirp
5. Firmly press the meter to a smooth flat surface with the sensor side of the meter (back) touching the material under test and wait for the display to stabilize; Note the value on the LCD.
6. The meter’s audible tones will sound as the reading changes. A blinking reading with an urgent chirping sound indicates that the measurement is out of the range of the instrument’s capability. Try another range by selecting another material group (see material group & range tables below)
7. Press and hold the HOLD button to freeze a displayed reading
8. If the meter goes into sleep mode, press the MEASURE button to wake it up. If the meter does not wake or if the low battery icon appears on the LCD, replace the 9V battery located in the rear battery compartment
9. Turn the rear power switch to OFF when meter is not in use. This will optimize the battery life
