Calibration instruments for the calibration of measuring instruments

WIKA offers a wide product portfolio of calibration instruments for the calibration of your measuring instrument in all accuracy classes, from a simple hand-held instrument to a primary standard, all with different levels of automation. A large number of patents ensure unmatched performance characteristics. We use the calibration instruments from WIKA in our own production and our accredited laboratories.

With a calibration instrument from WIKA, pressure measuring instruments from -1 … 10,000 bar can be calibrated at an accuracy of 0.003 % of reading. With the calibration instruments for temperature, calibration of your temperature measuring instrument is possible in the range of -196 … +1,600 °C (control range -55 … +1,100 °C). In our product portfolio of calibration instruments for electrical measurands you can find, among others, process calibrators, multi-function calibrators and standard reference resistors. In addition, for the measurand of length, we offer the calibration of both your measuring test equipment and reference gauges.

How to calibrate a pressure gauge?

Calibration means the determination of the deviation of a measuring device in comparison to a reference device that measures extremely accurately. The calibration of a pressure gauge is performed with the use of a reference measuring device. By comparing the pressure gauge with the extremely accurate reference instrument, deviations can be detected. When performing the calibration, the entire measuring range is taken into consideration, thus the zero point as well as the intermediate and final values are checked. If the deviation is within the manufacturer's specifications, the pressure gauge receives the calibration certificate.

This process is to be distinguished from the adjustment. Adjustment is performed when the deviation of the calibration is too large, therefore does not match the manufacturer's specifications.

FAQ
FAQ

What is the difference between the factory calibration and the calibration in accordance with ISO 17025?

The difference is that the factory calibration only documents the deviation from the reference, while ISO 17025 calibration ensures traceability to the national standard. In addition, along with the deviation, the hysteresis and the repeatability are ...
