Silicon photo-multipliers (SiPMs) are currently progressively replacing photo-multipliers tubes (PMTs) in most applications due to their technical advantages, specially in high energy physics experiments. This work describesa system to test photo-detectors in order to calibrate and characterize the parameters generally defined by scientificprojects requirements. The system controls and monitors different variables, as temperature, polarization bias,controlled light-source emission, and chamber humidity. It is included in this document the calibration results for a SensL MicroFC-SMA-30035 SiPM and its operation under workingthermal conditions, such as the expected for an atmospheric Cherenkov telescope detector. First results show that theusage of this SiPM in a telescope is feasible concerning the expected thermal excursion.
