Sensor Reconditioning: Over time, the internal sensor may be compromised as a result of pollutants, chemical vapors, and other environmental conditions which can lead to inaccurate readings.

To recondition the internal sensor, please follow this procedure. Dry the logger at 176°F (80°C) at less than 5% RH for 36 hours followed by 70° to 90°F (20° to 30°C) at >74% RH for 48 hours (for re-hydration). If permanent damage to the internal sensor is suspected, replace the Logger immediately to ensure accurate readings.
