Quantum Photon Par Sensor

We are engaged in manufacturing, exporting and supplying excellent quality Quantum Photon PAR Sensor in Padova, Veneto, Italy. Photo-radiometric probes with output signal in mV or standard output 4A.20mA or 0A.10Vdc.
The probes of the series LPPAR03 for outdoor use allow to measure the photon flow across the PAR region (400nm...700nm).
The probes with mV output do not require any power supply. The output signal is obtained from a resistance that short-circuits the terminal of the photodiode. The ratio of generated photocurrent to incident light power is converted into a Difference of Potential that can be read by a voltmeter. Once the DDP (Difference of Potential) is known, the measured value can be calculated through the calibration factor. All probes are individually calibrated and the calibration factor is also shown on the probe housing.
