Calibration of test and measurement instruments
We calibrate electrical measuring instruments for DC and Low Frequency as well as devices for measuring temperature and humidity. Equipping our laboratory with high-quality standards from renowned companies FLUKE and WAVETEK allows us to check multimeters up to 7 ½ digits. Instruments with a GPIB interface can also be calibrated in a fully automatic system. We provide measurement consistency with reference to national standards. All our reference instruments have the required certificates and a documented history.
We calibrate the following measuring instruments:
- Multimeters, Voltmeters, Ammeters,
- Current Clamps, Ohmmeters,
- Resistors, Oscilloscopes, Power Supplies,
- Multifunction Calibrators, Insulation Resistance Meters,
- Temperature and Humidity meters and sensors
