| definition | The Middleton SK01-DP2 PAR Sensor (or Quantum Sensor) is for measuring electromagnetic radiation at Photosynthetically Active wavelengths. It uses a silicon photodiode detector, shielded by a cosine-corrected diffuser and an interference reflector, to measure PAR on a horizontal surface. The detector is boosted by a low noise amplifier that is drift stabilised. The SK01-DP2 features: viewing angle 2*pi steradians; spectral range of 400-700nm; irradiance of 0-3000 umol/s/m2; sensitivity of 0.5 mV/umol/s/m2; response time (to 95 percent) of 30 ms; operating temperature of -35 to 60 degreesC; non-linearity of less than 1 percent; spectral response of +/- 5 percent. | ||||||
