SP-610-SS Downward-Looking Thermopile Pyranometer

$325.00

The SP-610 is a downward-looking thermopile pyranometer with an analog output range of 0 to 300 mV. The sensor incorporates a blackbody thermopile detector and flat glass window with a rugged housing design. Typical applications include shortwave radiation measurement in agricultural, ecological, and hydrological weather networks. Sensors are also used to optimize photovoltaic systems.

These sensors can be coupled with an upward looking pyranometer to form an albedometer. For this configuration, we recommend using our AL-130 Albedometer Mounting Bracket. Sensor includes IP68 marine-grade stainless-steel cable connector 30 cm from head to simplify sensor removal and replacement for maintenance and recalibration.
