Factory Calibration

LI-192 and LI-193 Underwater Quantum Sensor recalibration is recommended every 2 years after field deployment.

What's included with factory recalibration?

The factory recalibration includes:

Calibrations of quantum and photometric 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. 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.
