The Pyranometer Sensor is calibrated to measure the shortwave radiation reaching the Earth's surface, measured in Joules m-2 s-1 or Watts m-2.
Apogee's unique self-cleaning dome-shaped head prevents water accumulation. The sensor head is potted solid to prevent internal condensation in humid environments.
In addition to the standard SP-110 pyranometer, there are also 2 models available with amplified outputs up to 2.5 or 5V.
Output: Responsivity 0.200 mV per W m-2; In full sunlight 220 mV (1,100 W m-2)
Sensitivity: Custom calibrated to exactly 5.00 W m-2 per mV
Input power: None, self-powered
Operating environment: - 40 to 55 °C; 0 to 100% relative humidity. Designed for continuous outdoor use. Can be submerged under water (with or without mounting screw).

Pyranometer Meters - MP-100 & MP-200
For portable monitoring, Apogee now have two meters for measuring solar irradiance. MP-100 includes and integral sensor, while MP-200 has a seperate sensor on cable.
A leveling base AL-100 is required for mounting light sensors.
