Apogee Silicon Cell Pyranometers


SP-110, SP-212, SP-214, SP-215, SP-230, SP-420, SP-421, SP-422

For measurement of total solar irradiance

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.

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.

 

Accessories

Leveling Bases

The AL-100 is required for sensors on cable.

The AL-210 is used for mounting meters with integral sensor.

AL-100 Solar Sensor Leveling Plate
Carry Case The AA-100 carry case is an optional accessory for protecting meters in the field AA-100 Front
Mounting Brackets

The AM-110 fits the AL-100 leveling base and can be mounted directly to a mast or pipe with an outer diameter of 33-53 mm.

The AM-001 is designed to fit to the back of a meter for mounting a sensor on cable.

Sensor Wands

The AM-310 is for placing sensors in difficult to access places, such as underwater or under canopy.

The AM-320 is a salt water version.
