* 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.
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.
