Overview
The CS300, manufactured by Apogee Instruments, measures total sun and sky solar radiation for solar, agricultural, meteorological, and hydrological applications. Its spectral range of 360 to 1120 nanometers encompasses most of the short-wave radiation that reaches the Earth's surface. This pyranometer connects directly to our data loggers. Its output can be measured by our data loggers.
Key Advantages
Ideal for long-term deployment in harsh conditions
Technical Description
The CS300 uses a silicon photovoltaic detector mounted in a cosine-corrected head to provide solar radiation measurements. Its dome-shaped head prevents water from accumulating on the sensor head. To eliminate internal condensation, the sensor head is potted solid and the cable is shielded with a rugged Santoprene casing. The CS300 is calibrated against a Kipp & Zonen CM21 thermopile pyranometer to accurately measure sun plus sky radiation.

Common Accessories
(2)18356
Apogee Pyranometer Leveling Base
The 18356 provides several functions:It provides a secure, stable mount for the CS300. A bolt secures the pyranometer to the leveling base.The bubble level and three leveling screws allow the pyranometer to be adjusted to level for accurate solar radiation measurements. 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.

Services
(2)30008
CS300/1, CS305, CS320, SP230/SS, or CS310 Calibration with Data
The 30008 provides a calibration of the CS300, CS305, CS320, or SP230-L Apogee pyranometer with a certificate. An RMA (Return Material Authorization) from Campbell Scientific is required.
Orderable33476
Solar Sensor ISO 17025 Accredited Calibration to ASTM E824 with Data
The 33476 calibration service is performed using a reference group of pyranometers traceable to World Radiometric Reference (WRR). This calibration is ISO 17025 accredited to ASTM E824 standard.

Compatibility
Sensor Mounts
Accurate measurements require the sensor to be leveled using a 18356 leveling fixture. This leveling fixture incorporates a bubble level and three adjusting screws. The 18356 mounts to a crossarm or a tripod or tower mast using the CM225 mounting stand. The CS300 should be mounted away from all obstructions and reflective surfaces that might adversely effect the measurement.
Data Logger Considerations
One differential analog input channel per probe is required.
