General Information
1.1 Instrument Function
The LI-189 is compatible with all LI-COR type 'SA' radia-
tion sensors. With these sensors the LI-189 can make in-
stantaneous measurements of Photosynthetically Active
Radiation (PAR) in air or water, illuminance in units of lux
or footcandles, and solar irradiance (W m
-2
).
1.2 Sensors
The LI-189 is compatible with all LI-COR type 'SA' radia-
tion sensors, which utilize a BNC connector.
LI-COR type 'SB' radiation sensors are also compatible if
the Calconnector (Calibration connector) is detached from
the BNC connector.
LI-COR type 'SZ' radiation sensors are not compatible with
the LI-189; they may, however, be fitted with a BNC con-
nector. Contact LI-COR for further information.
Recalibration of all LI-COR radiation sensors is rec-
ommended every two years.
