Interchangeability of rH/T Sensors
All humidity sensors are factory-calibrated with SCS calibration solutions and subsequently receive a calibration certifica-te.
The adjustment points are 0%rH and 80%rH. (95%rH for high levels of humidity)
The ECOLOG rH/T sensors are interchangeable in their pre-calibrated state. The calibration data are read in by the logger.

Ecolog-Net LH2 - Calibration or Adjustment
We recommend that humidity sensors used in normal working environments are calibrated every 6 to 12 months.
If necessary, they should also be readjusted.
Use our SCS-certified humidity calibration solutions for opera-ting points with relative humidity values of 0%, 5%, 10%, 20%, 35%, 50%, 65%, 80% and 95%.
Verification is more important than adjustment!  
The calibration solutions and the calibration device can be used to simulate a variety of humidity levels at the sensor.
Single-point adjustment of the upper adjustment point with the 80% calibration solution is suitable for the majority of applications.
The following material and equipment are required:

• a calibration device (Part No. 102-2902)
  

• calibration solution of 0% .. 95% (Part No. 102-2901-Hxx)
  

• extension cable 1m (Part No. 102-3215-S01)
  

• calibration case or thermally isolated boxor calibration set for 0% and 80% (Part No. 102-2812-B)
