Overview
The SQ-110 measures photosynthetically active radiation and is calibrated for use in sunlight. Its spectral range of 410 to 655 nanometers. This quantum sensor connects directly to our data loggers. Its output can be measured by all of our data loggers (except the CR200X).
The "-L" on a product model indicates that the cable length is specified at the time of order.

Technical Description
The SQ-110 consists of a cast acrylic diffuser (filter), photodiode and a signal processing circuitry mounted in an housing to provide photosynthetically active radiation (PAR) measurements for solar, agricultural, meteorological, and hydrological applications. Calibrated through side-by-side comparison to the mean of four Apogee model SQ-120 transfer standard quantum sensors under high output T5 cool white fluorescent lamps.

Compatibility
Sensor Mounts
Accurate measurements require the sensor to be levelled using a AL-100 levelling fixture. This levelling fixture incorporates a bubble level and three adjusting screws. The AL-100 mounts to a tripod or tower using the CM225 mounting stand. For most applications, Campbell Scientific recommends attaching the CM225 to a CM202, CM204, or CM206 crossarm. The CM225 can also be attached to a tripod or tower mast.
Data Logger Considerations
One differential analog input channel per probe is required.
