Regular calibration of all measurement equipment is the key to maintaining the original performance and accuracy. We recommend calibration of the sensitivity of our radiometers every two years.

The individual sensitivity of a Kipp & Zonen 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.

Service & Repair

Kipp & Zonen products are designed for a long operating life and most components, other than consumables used in regular maintenance, do not have a specific life-time.

However, components do degrade or require servicing to maintain optimal performance depending upon age, the operating conditions and maintenance.

It sometimes happens that products become damaged by accident or by extreme conditions (such as lightning strikes). In this case repairs and the replacement of parts will be necessary.
