PAR1 Photosynthetically Active Radiation Sensor,
The PAR1 sensor measures the ratio between the number of photons in the 400 to 700nm spectral range that strike a surface in one second, and the surface area (in m²). This quantity is defined as PAR: Photosynthetically Active Radiation.
Thanks to the particular geometry of the PAR1 sensor it has a visual range of 180 degrees.
A typical application that requires the installation of a PAR sensor is indoor (e.g. in greenhouses) and outdoor research of plant development, for which PAR-1 is perfectly suited, delivering a cost effective solution. Please note that in particular for outdoor applications frequent cleaning of the sensor lense with a soft, damp cloth is recommended, as dust on the diffuser surface will reduce its accuracy.
To ease installation Adcon has integrated a signal amplifier into the device that linearizes the output to a uniform 0...2,5V signal, compatible to the analog inputs of all Adcon RTUs, making this a plug-and-play sensor.
The sensor comes complete with all mast mounting equipment, two pipe clamps, and a shielded 2m cable with a 7-pin Binder jack, compatible to all RTU's of the A723, A733 and A75x families.
