Lower power states can be achieved by less frequent sampling and remote control of heaters.
Optional power supplies with battery backup available.
Connectors in place of flying leads are available.
A low-voltage shutdown level can be set to prevent backup batteries from being damaged.

Lens contamination circuity monitors both the source and detector lenses for contamination/blockage at 1 s intervals.
The sensor can be configured to adjust calibration for low to moderate window contamination.
Light source stability control ensures stable operation through variations in temperature and with sensor aging.
Corrected at 1 s intervals.
|Emitter Light Frequency||850 nm|
Please note: The following shows notable compatibility information. It is not a comprehensive list of all compatible products.
CR1000X programs that read continuous data and polled data and use the SET, SETNC, and GET commands. The program that uses the SETNC command powers the CS125 hood heaters when needed according to the dew point. A HydroVUE5 Air Temperature and Relative Humidity Sensor provides the measurements used in the dew point calculation.
Includes the current CS120A and CS125 firmware.
Note: This is not applicable for the original CS120 sensor.
Campbell Viewpoint is viewing software designed to accompany the Campbell Scientific optical sensor range, including the CS135 ceilometer, SkyVUE PRO, SkyVUE 8, SkyVUE 8M, CS120A visibility and CS125 present weather sensors. It is free to download (or via email on request) and use for 100 hours, after which you will need to purchase a key to continue using it.
Viewpoint version 188.8.131.52 has introduced our new ceilometer sensors to the list of instruments that can be monitored. This includes the SkyVue PRO, SkyVUE 8 and SkyVUE 8M.
Previous sensors are still available.
Version 184.108.40.206 also includes some minor bug fixes and improvements to the help menu.
