Humidity Measurement Operating and Storage Conditions

This chart shows the normal recommended operating range of the LogTag Humidity sensor. Conditions outside the recommended range may temporarily offset the RH signal up to ±3%RH. After return to normal conditions, the LogTag humidity sensors will slowly return towards calibration state by itself. Prolonged exposure to extreme conditions may accelerate the aging of the HAXO-8 datalogger.

Re-Conditioning Procedure

Exposure of the internal sensor to chemical vapors can interfere with the internal logging sensors and cause inaccurate readings to be recorded. In a clean environment, this will slowly be self-corrected. However, exposure to extreme conditions or chemical vapors will require the folowing reconditioning procedure to bring the internal sensor back to calibration state.
1. 80°C (176°F) at <5%RH for 36 hours (baking) followed by
2. 20-30°C (70-90°F) at >74%RH for 48 hours (re-hydration).High levels of pollutants may cause permanent damage to the internal datalogging sensors.

Exposure to Chemicals

Chemical vapors may interfere with materials used for the humidity sensor. The diffusion of chemicals into the sensor\'s polymer may cause a shift in both offset and sensitivity. In a clean environment the contaminants will slowly dissipate. The reconditioning procedure will accelerate this process. High levels of pollutants may cause permanent damage to the humidity sensor\'s polymer.
