Common Accessories

The LI2003S, manufactured by LI-COR, is required to attach an LI200X pyranometer or LI190R quantum sensor to our CM225 solar sensor mounting stand, 015ARM mounting arm, or 025STAND crossarm stand.
The CM225 attaches one pyranometer or quantum sensor to a mast, crossarm, or pole (1.0 to 2.1 in. OD). Many pyranometers and quantum sensors also require a leveling base that secures the sensor to the CM225 as well as level the sensor.
The 015ARM is used to attach a pyranometer or quantum sensor to a tripod. Many pyranometers and quantum sensors also require a leveling base that secures the sensor to the 015ARM and levels the sensor.

Other Accessories

The 31977 is used to protect the LI190R-L base and internal connector when the sensor head is removed.

Replacement Parts

The 31976 O-ring is used to seal the LI190R, LI200R, and LI200RX sensor head/base assembly.
The 32217 Replacement Sensor Head has a different calibration value than what is presently used in the field and what is written on the sensor cable. Remember to update your program with the new multiplier to match the new head. When replacing the sensor head, do not leave the bottom of the sensor assembly uncovered for long periods in the field. If the sensor head cannot be swapped out immediately, cover the sensor base using pn 31977 Sensor Base Cover until a new sensor head can be installed.


The response of the LI190R sensor to solar radiation is calibrated at LI-COR. If LI-COR repairs the housing, cable, or photodiode, additional repair charges will apply. All factory recalibrations require an RMA (Returned Material Authorization).
