Regular calibration of all measurement equipment is the key to maintaining the original performance and accuracy. The individual sensitivity of a radiometer is determined under the measurement conditions stated on its calibration certificate and is valid at the date of first use. If the radiometer is carefully stored in dark, warm and dry conditions and desiccant is changed as required, the sensitivity will not change.
