PAR LITE
• Measurement of photo synthetically active radiation
• Can be used under
all weather conditions
• Easy to use
PAR Lite is designed for outdoor measurement of photo synthetically 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.
