Overview
The CS300-LQ, 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. The CS300-LQ is intended for continuous outdoor use.

Detailed Description
With this version of the CS300 pyranometer, the cable terminates in a military style connector and has a user-specified lead length. The connector attaches to the RAWS-P enclosure, which mounts to a CM6/CM10 tripod, CM110-series tripod, or UT-series tower.
The CS300-LQ 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.
Compatibility
This sensor has a cable with a user-specified lead length that terminates in a military style connector for attaching to the RAWS-P enclosure.
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.
