Skye Instruments have been specialising in light and radiation sensors since 1983. All are designed, manufactured and calibrated to the highest standards. Each is supplied with a Calibration Certificate traceable to the UK’s National Physical Laboratory (NPL).
There are three PAR sensors in the range, PAR Quantum, PAR Special and PAR Energy. All measure the Photosynthetically Active Radiation between 400-700nm, the part of the solar spectrum used by plants for photosynthesis and sugar production.
The most popular is the PAR Quantum sensor, which is used to measure photon irradiance, or quantity of PAR light. It is calibrated in units of μmol m-2 s-1 (number or quanta of photons).
Skye sensors are suitable for use in natural solar radiation or any lamp or light source. Each is fully waterproof and guaranteed submersible to 4m depth. Indoor versions are also available.
The Skye PAR sensors are compatible with Skye Display Meters, SpectroSensor meters and DataHog loggers. A choice of outputs are also available to suit most dataloggers and controllers.
