Frequently Asked Questions

Q. What is a reference thermometer?
A. A reference (or master) thermometer is a highly accurate device used to check and validate the performance of other thermometers by comparison against a stable temperature source.

Q. How is it used?
A. It is placed in the same environment as the device under test—often within a calibration bath or dry block—and readings are compared to identify any deviation.

Q. Why is high accuracy important?
A. Greater accuracy ensures confidence in calibration results, helping maintain compliance and measurement reliability across critical processes.

Q. Does it include certification?
A. Yes, each unit is supplied with a 5-point UKAS calibration certificate for traceable accuracy verification.
