CAUTION
Exposure of the internal sensor to chemical vapours such as those produced by some plastics and foamed materials
may interfere with the internal sensor and cause inaccurate readings to be logged. In a clean environment, this will
slowly rectify itself, therefore ensure that the logger is used in a ventilated area i.e. air exchange is allowed.
Exposure to extreme conditions or chemical vapours will require the following reconditioning procedure to bring
the internal sensor back to calibration state. 80°C (176°F) at <5%RH for 36h (baking) followed by 20-30°C (70-
90°F) at >74% RH for 48h (re-hydration).
High levels of pollutants may cause permanent damage to the internal sensor.
