Common Accessories

The 18356 provides several functions:
  1. It provides a secure, stable mount for the CS300. A bolt secures the pyranometer to the leveling base.
  2. The bubble level and three leveling screws allow the pyranometer to be adjusted to level for accurate solar radiation measurements.
  3. The base can be attached to a CM225 Solar Sensor mount using three mounting screws which allows the pyranometer to be deployed on a variety of instrument mounts.
The CM225 Solar Sensor Mounting Stand attaches the CS300 to a crossarm, mast, or pole with a 1.0" to 2.1" OD.


The 30008 provides a recalibration of the CS300, CS305, CS320, or SP230-L Apogee pyranometer with a certificate. An RMA (Returned Material Authorization) from Campbell Scientific is required.
The 33476 recalibration service is performed using a reference group of pyranometers traceable to World Radiometric Reference (WRR). This recalibration is ISO 17025 accredited to ASTM E824 standard.
