LI-COR Quantum Radiometer Photometer LI-189 (11163) Check Availability

The LI-189 light meter has one BNC input port that accepts LI-COR light sensors. With these sensors the LI-250 can measure photosynthetically active radiation (PAR) in air or water, illuminance in units of lx or fcd, and solar irradiance in units of Watts/m^2. The accuracy of the device is typically ± 0.3 % ± 1 digit of the reading at 25 °C and ± 0.4 % ± 3 digits from 0 to 55 °C.
