General Description



Quantum Scalar Irradiance PAR Surface Reference Sensor. Data output may be chosen between volts, volts‐offset (default), calibrated irradiance, or calibrated irradiance adjusted for immersion in water. Optionally, sensor temperature and line voltage may be included in the data stream. A preamble may be defined to the data frame to easily identify data in a multi‐sensor environment. For example "$" may be used in a NEMA application. As delivered, the output is in volts‐offset.
