LI-COR LI-200SA Solar Radiation Sensor

Details:

An industry standard for more than 30 years, LI-COR radiation sensors provide research grade data at an economical cost. The LI-COR 190 Quantum Sensor measures photosynthetically active radiation (PAR), and the LI-COR 200 Pyranometer measures global solar radiation, suitable for measuring global sun plus sky radiation.

The 2003S Mounting and Leveling Fixture is recommended for each sensor to ensure proper mounting. The M-ARM mounting arm is a 3' aluminum unistrut kit which includes a U-Bolt for mounting to poles less than 2 3/8" in diameter as well as a stainless steel bracket that allows for the 2003S leveling fixture to screw directly onto the arm.

Type SZ sensors end in bare wires and deliver a microamp current output; type SA sensors require a millivolt adapter for connection with NexSens iSIC data loggers. Data collection options include direct-connect, landline phone, cellular, radio, Ethernet, WI-FI, and satellite telemetry. NexSens iChart Software is a Windows-based program for interfacing both locally (direct-connect) and remotely (through telemetry) to a NexSens data logger or network of data loggers.
