No. The sensor cannot be calibrated, but Campbell Scientific can perform a calibration verification that includes multiple points (temperature and relative humidity). Campbell Scientific recommends using three points for RH (10%, 50%, and 90%) at one temperature (25 degrees Celsius), as well as an additional temperature point. This verification process has an initial setup charge and an additional per-point charge. Campbell Scientific sends a document indicating the values tested to with the accompanying measurement from the associated sensor.
