Dear Brothers,
I’m using infrared thermometer for crosschecking and verifying kitchen cold rooms and refrigerators.
Is it necessary to calibrate the used thermometer to comply with ISO 9001 standards 7.6 “control of monitoring and measuring equipment?
In addition of that, the thermometer costs $150, and calibration services expense is around $95. 
Please need your advice for this matter, and how can I properly implement clause 7.6 in this case.
Thanks
