Moisture Meter Specifications
Internal Pinless Sensor Measurements 0 to 100 (relative readings)
External Pin-based Measurements 7% - 30%* (±1.5% MC*)
30%-100%* (Reference Only)
Measurement Resolution 0.1
Pinless Measurement Depth 1.9cm (0.75”) maximum
Pin Moisture Groups Nine (9) material groups
Response time Pinless mode: 100ms
Pin mode: 750ms
Notes:
* Maximum specified range is dependent on the fiber saturation point for specific species. Beyond this point, the
reading can only be used as a relative reference value. For more information on fiber saturation please refer to
ASTM D7438. Accuracy specification is based on the analysis in J. Fernández-Golfín et al. Actual real-world
accuracy depends on a variety of factors; For more information, refer to ASTM D4444, section 6.
**Accuracy spec. applies to pin probe moisture measurements taken on wood whose temperature is 20°C
(70°F). Add 0.1% to the accuracy spec. for each °C below 20 or subtract 0.1 for each °C above 20.

Relative Humidity Sensor Note:
The meter should be stored in an environment with a relative humidity similar to the area to be tested. If the
storage humidity differs by more than 50% RH from the area under test, an acclimation period of up to 24 hours
may be required to meet the specified RH accuracy.
