HP 81531A Optical Power Sensor Calibration and Repair Services
Simbol Test Systems provides professional in-lab HP 81531A InGaAs Optical Power Sensor calibration and repair services to help maintain accurate, reliable performance for your optical power measurement equipment. All calibration services are performed in our laboratory using documented procedures, traceable standards, and experienced technical staff.
The HP 81531A is an InGaAs-based optical power sensor module designed for use with the HP 8153A mainframe. It operates across the 800 to 1700 nm wavelength range. Simbol has had success repairing this type of module, depending on the condition of the unit and parts availability.
Our service process is designed to evaluate the condition of your HP 81531A optical power sensor, verify optical power measurement performance, and determine whether calibration, repair, or both are appropriate. If the unit shows measurement drift, connector issues, sensor-related problems, communication faults, or other operating issues, we can review the failure condition and provide service recommendations.
Following calibration, your equipment may be returned with a calibration label, calibration certificate, and related calibration data. If the unit does not successfully complete calibration, we can evaluate the repair requirements and provide a repair quotation for approval before proceeding.
Traceability: Instrumentation used during this calibration is traceable to N.I.S.T. (National Institute of Standards and Technology) or C.N.R.C. (Canadian National Research Council), where applicable.
