PAR LITE

PAR LITE is designed for outdoor measurement of photosynthetically active radiation (PAR) in natural daylight.
It has been specifically designed for:
Agricultural meteorology
Studies of crop growth

PAR LITE can be used under all weather conditions. The sensor measures the PAR received from the entire hemisphere. PAR LITE uses a specially designed optical filter to provide a spectral response between 400 and 700 nm.

PAR LITE uses a photodiode sensor, which creates a voltage output that is proportional to the incoming radiation.
PAR LITE is easy to use. It can be directly connected to voltmeter or data logger. By using the sensitivity a direct readout in µmol/m²·s can be derived. For each sensor the individual sensitivity is indicated on the instrument.
