Calibrators

Our range of calibrators includes single and multifunction devices from a large number of world class manufacturers. We provide primary references for use in laboratories and as site standards, as well as a range of field devices and units certified for use in potentially explosive hazardous areas.

Comparing different calibrators can be a confusing and exhaustive process as different manufacturers employ different methods to express (or in some cases, obscure) the accuracy / uncertainty of their devices. See our Calibration Tek-Tip for more information.
