Humidity Measurement Operating and Storage Conditions

Humidity Measurement Operating and Storage Conditions for LogTag Humidity and Temperature Data LoggerThis 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 HAX0-8 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.

  • Answer:

    The calibration certificate is an optional service that must be added to the order separately.  To select it choose one of the two options that are shown just above the "add to cart" button.  They are both the same service but one includes the uncertainty data on the certificate and the other doesn't.

  • Answer:

    The HAXO-8 logger does not have a replaceable battery.  Once the battery is depleted the logger must be replaced.

  • Answer:

    Yes, when you use the "add to cart" button for this product you are only purchasing the logger itself.  It will work in your existing docking station although depending on how old your software is you may have to update it for it to work properly.  We always recommend updating to the latest software version as they become available.  You can do this from your existing software by choosing "help" and then "check internet for update".

    This device would show you the temperature and humidity values of your attic throughout each day.  You would have to interpret that data to determine if the space is in the appropriate range or not.

  • Answer:

    The HAXO-8 logger is rated for IP61 which states it is dust tight and protected against occasional dripping water.  It has been our experience that long term exposure to condensing moisture can cause premature failure of the logger.  We recommend using a logger designed for outdoor use for this type of application or mount the logger in such a way that it is protected from direct exposure to condensing moisture.
