5.2 Moisture Measurements
5.2.1 Moisture Measurement Overview
Moisture measurements can be performed using either the internal pinless moisture sensor
(rear) or by connecting an external probe. A standard external pin probe is included which
connects to the MR176 via the jack at the bottom of the meter. Other external probes are
available; please visit
www.flir.com/test
for details.
NOTE: Objects in close proximity to the internal pinless moisture sensor (located on the rear of
the unit) will affect the reading on the display; Keep hands and fingers clear of the sensor when
taking measurements.
The internal moisture sensor detects moisture to a depth of approximately 19mm (0.75”). The
actual depth will vary depending upon the amount of moisture, the material under test, surface
roughness, and other factors.
Moisture readings are shown on the display (digitally and with bar graph) in the Moisture-only
mode or in small digits (upper left hand corner) in the IGM Custom and IGM Moisture modes.
See Fig. 5-1. Pinless measurement readings are ‘relative’ scaled (0~100). Pin-based readings are
represented in terms of %MC (moisture content) for wood and %WME (wood moisture
equivalent) for non-wood materials; additional information is provided in Section 5.2.6 External
Pin Probe Moisture Measurements and in the specifications.
Moisture measurements are covered in detail in the following sections. Be sure to select Pin
Mode or Pinless Mode in the Moisture Menu to match the measurement type.
