Pyranometers

15% Discount on Pyranometer Calibrations

IEC61724 recommends Class A sensors be re-calibrated once every 2 years, or more frequently per manufacturer recommendations and for Class B sensors, according to manufacturer recommendations.

To ensure an accurate and reliable measurement, and to stay compliant with IEC and WMO recommendations, we at OTT HydroMet suggest getting pyranometers re-calibrated every two years.

To this end we are offering the month of calibration for pyranometers, where you will not only get 15% discount per calibration but also a quick turn-around time.
