CMP11

The CMP11 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.

Key features

  • Secondary Standard Pyranometer
  • Excellent Linearity
  • Fast Response Time
  • Low Tilt Error
  • 5 year full warranty (*)

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 drying cartridge is now a screw-in type that can be simply removed using a coin, for changing the desiccant that is supplied in convenient refill packets.

The Pyranometer does not require any power, it supplies a low voltage of 0-20 mV in relation to the amount of incoming radiation. When a higher voltage level or a 4-20 mA signal is required, the AMPBOX is the perfect solution.

(*) This product will need to be registered by the end-user within 6 months of purchase to activate the 5 year warranty.
