The company that I work for has been working with Thermo Temp for a long time. They are experts in the calibration business. Yesterday, we had a great experience working with them. We needed to have a couple of gauges calibrated on the same day, and Chris worked closely with us to ensure that it happened quickly. We truly appreciate doing business with this company.
