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.

Unit works well. I had the earlier model THL1 and it would not work with Windows 7. The newer version now works with Windows 7. Thanks
