Overview
The CMP6 pyranometer is intended for routine global solar radiation measurement research on a plane/level surface. Fully compliant with ISO 9060:2018 specification for a Spectrally Flat Class B, the CMP6 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.
CMP6 has a similar detector to the CMP3 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 a dedicated power supply. It generates a low voltage output in the estimated range of 0 to 30 mV relative to an irradiance measurement range of 0 to 1500 W/m². When a higher voltage level or a 4 to 20 mA signal is required, the AMPBOX is the perfect solution.
Benefits
Well known for high quality, durability and accuracy. The CMP pyranometers require no power, so are ideal for remote sites.
ISO 9060 spectrally flat Class B, with ISO / IEC 17025 calibration.
Best MTBF with 5 years warranty.
