Enabling better global research outcomes in soil, plant & environmental monitoring.

PYR Pyranometer

The PYR Pyranometer is a simple, low cost yet highly accurate pyranometer for global solar radiation monitoring.

The PYR Pyranometer measures solar radiation between 380 and 1120nm and has a levelling plate. The PYR sensor is supported by the LSM Light Sensor Meter, Decagon Em50 Data Logger, or Procheck Hand Held Meter.

Measure Total Solar Radiation

The PYR total solar radiation sensor (pyranometer) measures the solar radiation flux density (in watts per meter squared) from a field of view of 180 degrees.

Weatherproof for Long-Term Use

The sensor is designed for continuous outdoor use, and is completely water proof and submersible.

Accuracy

Accurate measurement depends on cleanliness of the lens, and installation of the sensor at horizontal (180°). The sensor head has a domed diffusion disk to reduce the need for frequent cleaning. A levelling plate is included for accurate installation.
