Radiation sensor to measure different kinds of radiation

Pyranometer CMP6, WMO class 1


The CMP 6 pyranometer is intended for routine global solar radiation measurement research on a plane/level surface.

Fully compliant with ISO-9060 specification for a First Class pyranometer, the CMP 6 features a sixty-four thermocouple junction (series connected) sensing element. The sensing element is coated with a highly stable carbon based non organic coating, which delivers excellent spectral absorption and long term stability characteristics.

CMP 6 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 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 0-20mV in relation to the amount of incoming radiation. By using the Combilog no measuring amplifier is required.
