Middleton Solar - Model SK01-DP - Manual

The SK01-DP2 Photosynthetically Active Radiation Sensor (or Quantum sensor) is for monitoring the electromagnetic radiation regulating photosynthesis in plants. It uses a silicon photodiode detector, shielded by a cosine-corrected diffuser and an interference reflector, to measure PAR on a horizontal surface. It has a glass dome to keep debris off the diffuser. The detector signal is boosted by a low noise amplifier that is drift stabilised.
