Kipp and Zonen

Kipp & Zonen is the specialist in the measurement of solar and sky radiation, from the ultraviolet to the far infrared. They offer a complete range of high quality instrumentation and accessories, from reliable cost-effective products to the best performance available. Their pyranometers, for example, are used in meteorological networks around the world.

Furthermore, their expertise and close links with the scientific community have led to high-end solutions for the measurement of atmospheric properties such as stratospheric Ozone, UV Spectra and evapotranspiration.


Equinox Instruments now has a Kipp & Zonen calibration facility here in the UK where we can offer a better turnaround time than before. Outdoor calibration is also a possibility for specific radiometers. Every (re)calibrated instrument comes with a calibration certificate that:

  • is traceable to the world standard
  • includes a description of the calibration procedure

Our pyranometers series are calibrated according to the ISO 9847 standard.

Calibration certificates are issued in compliance with the requirements of the ISO/IEC 17025 and are recognised by all the major international accreditation organisations.
