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 MR160 via the jack at the bottom of the meter. Other external probes are
available; please visit www.flir.com/test for details.
NOTE: Objects near 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 19 mm (0.75 in.).
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 IR + IGM Moisture mode. See Fig. 5-1.
Pinless measurement readings are ‘relative’ scaled (0 to 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.

Notes on External Pin Probe Moisture measurements
The MR160 will display accurate external pin probe readings in the 7% to 30% range,
depending on the tested material. Moisture Content readings below 6% will display as 0% for
all materials and the maximum specified range is dependent on the fiber saturation point for
specific species. Above the fiber saturation point, the reading can only be used as a relative
reference value.
For more information on fiber saturation please refer to ASTM D7438. For additional
information on Pin moisture measurement accuracy please see ASTM D4444, section 6.
FLIR MR160 USER MANUAL Document Identifier: MR160-en-US_AG
15
5.2.7 Reference Mode Moisture Measurements
1. Follow the steps in Section 5.2.1 through 5.2.4 and select SET REFERENCE from the
MOISTURE mode options. This mode is only available for pinless measurements (internal
sensor).
2. When the SET REFERENCE mode is selected the displays are affected in the following
ways:
• IR + IGM Moisture image mode: A new display line will appear preceded by a delta
(triangle) symbol. The digits next to the delta symbol indicate the reference value
(the measurement recorded when the SET REFERENCE mode is selected).
• Moisture-only mode: The Reference value and delta symbol are shown on the right
side of the display, refer to example screen in Fig. 5-1(b).
3. All measurements taken subsequently will be relative to the reference value. For
example, if the reference value is ‘10’ (representing the driest area of the material under
test) and a measurement of ‘50’ is taken (in an area with higher moisture content), the
measurement line will show ‘40’ (50 – 10 = 40). As implied, this mode is useful for
comparing wet areas to a dry area reference.
4. To remove the reference value and exit the mode: Remove the meter sensor from the
area under test, so that the sensor is no longer touching a surface and is clear of any
objects (keep hands away from the sensor also), and then press the Set Reference icon
again. The reference value will no longer be visible on the meter display.
5.3 Thermal Imager (IR)
The full screen IR Thermal Imager is active in the IR -only mode and the IR + IGM
Moisture mode (selectable from the IMAGE mode icon in the Main Menu).
The Thermal Imager lens is located on the back of the meter. Face the lens toward the area of
interest and view the image on the meter display.
Select the IR thermal image display color palette from the Settings menu. Select IRON,
RAINBOW, ICE, or GREYSCALE; see examples in Fig. 5-4.
For example: the ICE palette hot to cold temperatures, for images, are represented by this color
palette progression: white>grey>black>blue>white. See the color palette example below in
figure 5-5(c). For the ICE palette, the right side of the scale shows the hotter pixels in the frame,
and the left side of the scale shows the coldest pixels.

5.4 Lock/Unlock Palette Auto-Scale Mode
Note: For best results, allow a warm-up period of 3-5 minutes before using this feature.
The Lock/Unlock Palette Auto-Scale option allows the color palette range to be adjusted to
suit a given application. For example, when viewing both cold and hot objects in the same
frame, the palette auto-scaling will cause the palette to be ‘stretched’ to fit the whole range
of temperatures. However, this can cause smaller temperature variations to disappear, as the
difference between two colors might increase from 1° to 10°. In this case, the user may
choose to lock the scale with only the cold or medium-temperature object in the frame. This
would cause the hot object to saturate but will provide more detail to the colder objects of
interest.
If the user wishes to narrow the range of color and limit it to colors near the cold temperature
image, Lock/Unlock can be set to ‘Lock’ with no hot objects in the frame. To lock the scale,
press the Select button to access the Main Menu, scroll to the Lock icon, and press Select
again to toggle unlock/lock. Some experimentation and fine-tuning may be required to get the
best possible contrast for the application.
5.5 Screen Capture and Hold
Pressing the Image Capture button captures the current MR160 screen. The screen will
hold (freeze) for seven (7) seconds, until an image filename appears indicating that the image
has been saved. During the seven second ‘hold’ period, the user can simply examine the image
and press the Back button to discard or press Select/Capture to save the image.
Images are saved in bitmap (.bmp) format. Images can be accessed on the MR160 screen using
the Image Review icon
available in the Main Menu. Then scroll the images using the Left and
Right navigation buttons.

image; choose ‘Cancel’ to keep the image.
Images can also be transferred to computer or other compatible device using the MR160 USB
port (bottom of meter, under flap) and supplied USB cable.
5.6 ‘Combination’ Feature: Save Thermal Image with Pinless Moisture Reading
The Combination feature allows the user to ‘freeze’ a thermal image and take a pinless moisture
reading, saving both the thermal image and the moisture reading on a single image. The ‘held’
thermal image, with continuous moisture reading shown on the same screen, can then be
captured as explained in Section 5.5 above.
1. Enter the IR + Moisture Image mode (refer to Section 5.2.3 Image Mode).
2. Hold the Image Capture button until crosshairs appear, and the laser is visible (Fig. 5-
7(a)).
3. While continuing to hold the Capture button, aim the laser at the measurement spot.
