LI-190R and LI-191R Factory Calibration

LI-190R and LI-191R (and the LI-190 and LI-191) Quantum Sensor factory calibration is recommended every 2 years after field deployment.

What's included with factory recalibration?

The factory recalibration includes:

Calibration coefficients of quantum sensors at LI-COR are obtained using standard light sources that are traceable to NIST. Sensor spectral response conformity is measured using a computer-controlled spectrophotometer and reference silicon photodiodes.

  • Sensors are cleaned prior to the calibration, inspected for diffuser and/or cable aberrations, and repaired as needed. Customer is notified if additional fees are required for repairs.
  • The sensor’s relative spectral response is measured to check its conformity to the ideal response. With the exception of the LI-191R, the sensor’s actual response is then run through the spectral error routine which calculates the theoretical reading errors that would occur with a variety of light sources to check for acceptable limits.

Request Service and Recalibration
