Overview
The CS305-ETM pyranometer, manufactured by Apogee, is similar to the CS300 but uses a different fixed multiplier and includes a leveling mount.
Key Advantages
Ideal for long-term deployment in harsh conditions
Technical Description
The CS305-ETM measures total sun and sky solar radiation using a silicon photocell. The spectral range is 300 to 1000 nanometers, which encompasses most of the shortwave radiation that reaches the Earth's surface.
The standard output is 0.005 mV per W m-2, which provides a signal of 5 mV in full sunlight (1000 W m-2). All our data loggers, except the CR200(X) series, can measure this output. Therefore both the ET107 and ET106 are compatible.
Benefits
- Dome-shaped head prevents water from accumulating on the sensor head
