Reliable all-weather performance
The widest range of pyranometers and accessories available

Pyranometers are radiometers designed for measuring the irradiance on a plane surface resulting from radiant fluxes in the wavelength range from 300 to 3000 nanometers. Kipp & Zonen has been manufacturing pyranometers for over 75 years.

The instruments are used in meteorology, solar energy research, material testing, climate control in greenhouses, building physics science and many other applications. Kipp & Zonen can supply a full range of pyranometers and accessories, according to the ISO 9060 and World Meteorological Organisation (WMO) standards.

Common characteristics of the pyranometers are the robustness, and all-weather performance. The instruments are easy to use, require no power, and are all supplied with calibration certificates that are traceable to WRR (World Radiometric Reference). For ease of mounting, exchange and recalibration the instruments have a waterproof connector.

The standard supplied 10 m shielded cable has the waterproof sealed counterpart connector. The comparison table shows the specifications, dimensions and options of the various types and helps selection of the right model for a specific application.

In the range of secondary standard pyranometers, Kipp & Zonen supplies equipment with special features; record breaking response time, exceptional levelling accuracy and a test certificate also covering the directional and temperature responses. These important parameters ensure the highest accuracy measurements.

is smaller and lighter than all other CMP pyranometers. It has a robust 4 mm dome to protect the thermopile from external influences. A spirit level and leveling screws are mounted in the base of the pyranometer. The small size and sealed construction make this instrument the ideal choice for agricultural and industrial applications and networks.

has a similar detector to the CMP 3, but has improved performance due to the increased thermal mass and the double glass dome construction. It is ideal for cost-effective, good quality, measurements in hydrological networks and agriculture. The connector with gold-plated contacts allows for easy exchange and re-calibration.

uses higher quality glass domes and a version of the detector technology originally developed for the CM 22 and is a step up in performance from the CMP 6. It is particularly suitable for meteorological networks and the reduced response time of 1.66 seconds (63 %) meets the requirements for solar energy applications.

has the same detector as the previous CM22 and individually optimised temperature compensation. A standard thermistor sensor is fitted to monitor the housing temperature. Each instrument is supplied with its own temperature and directional (cosine response) test data. It is the choice for scientific use and in top level solar radiation monitoring networks such as the BSRN (Baseline Surface Radiation Network) of WMO.

To create an albedometer two CMP 3's can be mounted opposite to each other. A rod can be screwed in one of the housings for fixating the mounted instruments to a mast. Each sensor has a separate cable that can be fixed along the mounting rod.

The combination of a pyranometer and shadow ring CM 121B offers a simple solution to the problem of measuring diffuse radiation from the sky. The shadow from the ring covers the pyranometer dome completely. The ring will not need adjustment for several days.

is smaller and lighter than all other CMP pyranometers. It has a robust 4 mm dome to protect the thermopile from external influences.

CMP6
has a similar detector to the CMP 3, but has improved performance due to the increased thermal mass and the double glass dome construction. It is ideal for cost-effective, good quality, measurements in hydrological networks and agriculture. The connector with gold-plated contacts allows for easy exchange and re-calibration.
CMP11
uses higher quality glass domes and a version of the detector technology originally developed for the CM 22 and is a step up in performance from the CMP 6. It is particularly suitable for meteorological networks and the reduced response time of 1.66 seconds (63 %) meets the requirements for solar energy applications.
CMP21
has the same detector as the previous CM22 and individually optimised temperature compensation. A standard thermistor sensor is fitted to monitor the housing temperature. Each instrument is supplied with its own temperature and directional (cosine response) test data. It is the choice for scientific use and in top level solar radiation monitoring networks such as the BSRN (Baseline Surface Radiation Network) of WMO.
CMP22
has all the features of CMP 21 but uses very high quality quartz domes for a wider spectral range, improved directional response, and reduced thermal offsets. Because of the high optical quality of these domes the directional error is reduced below 5W/m2. Kipp & Zonen is confident that CMP 22 is the best Pyranometer currently available.

	To create an albedometer two CMP 3's can be mounted opposite to each other. A rod can be screwed in one of the housings for fixating the mounted instruments to a mast. Each sensor has a separate cable that can be fixed along the mounting rod.
	CV 2 ventilation unit is designed for use with all CMP pyranometers (except the CMP 3) Ventilation and two levels of heating will improve the reliability and accuracy of the measurement under all weather conditions. Ventilation will keep the dome clean from precipitation and snow plus suppresses the infrared offset by stabilization of the dome temperature.

	The 2AP tracker is an all-weather, reliable and affordable tracking and positioning instrument. It is used to accurately point small and medium sized payloads, either as a dedicated Sun tracker or as a computer based Positioner. A wide range of accessories is available for mounting instruments and adaptation to extreme climate conditions. The 2AP specification match with the requirements for BSRN stations. (Baseline Surface Radiation Network)
	AMPBOX is a current loop amplifier for the complete range of pyranometers. Pyranometers have output signals in the mV range, the AMPBOX can amplify this to a 4 - 20 mA level. Amplification is advised for noisy environments, read-out equipment with high-level inputs and for very long (> 100 m) cables.
