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 shortwave radiation that reaches the Earth's surface. This pyranometer connects directly to our dataloggers. Its output can be measured by all of our dataloggers.

Benefits and Features
- Compatible with most Campbell Scientific data loggers
- Designed for continuous, long-term, unattended operation in adverse conditions
- Measurement waveband of 360 to 1120 nm
- Dome-shaped head prevents water from accumulating on the sensor head
The "-L" on a product model indicates that the cable length is specified at the time of order.

Detailed Description
The CS300 uses a silicon photovoltaic detector mounted in a cosine-corrected head to provide solar radiation measurements for solar, agricultural, meteorological, and hydrological applications. Calibrated against a Kipp & Zonen CM21 thermopile pyranometer, the CS300 accurately measures sun plus sky radiation for the spectral range of 360 to 1120 nm. Sensors calibrated to this spectral range should not be used under vegetation or artificial lights.
The standard output is 0.2 mV per W m-2, which provides a signal of 200 mV in full sunlight (1000 W m-2). All of our dataloggers, including the CR200(X) series, can measure this output.

Additional Compatibility Information
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.
