The LI-COR 190 Quantum Sensor accurately measures photosynthetically active radiation (PAR).
Features
Provides research grade data
Measures photosynthetically active radiation (PAR)
Cable ends in flying leads for connection with a data logger
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. Type SZ sensors end in bare wires and deliver a microamp current output; type SA sensors require a millivolt adapter for connection with a data logger. A 2003S Mounting and Leveling Fixture is recommended for each sensor to ensure proper mounting.
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.
