The CMP11 pyranometer uses the temperature compensated detector technology originally developed for the CMP22 and is a step up in performance from the CMP6. It is particularly suitable for meteorological networks and the reduced response time of 1.66 seconds (63%) meets the requirements for solar energy applications.

A waterproof socket is fitted for the signature yellow signal cable, which is available in a range of lengths pre-wired to the waterproof plug.

The integral bubble level is raised to the top of the housing and can be viewed without removing the redesigned snap-on sun shield, which also covers the connector. The connector with gold-plated contacts allows for easy exchange and re-calibration. The screw-in drying cartridge is easy to remove and the replacement desiccant is supplied in convenient refill packets.

The pyranometer does not require any power, it supplies a low voltage of 0 to 20 mV in relation to the amount of incoming radiation.
