Electro Technical including RF Calibration

In Electrical, customers conducting testing/ measurements are dealing with people's safety and they are carrying an extended duty of care not only ensuring that the equipment’s are safe, but that it is fit for purpose and not posing serious risk to others and public in general.

Electrical instrument calibration involves the use of precise devices that evaluate the performance of key properties for other devices called “Unit Under Calibration” (UUCs). Because these precise devices have thoroughly known performance characteristics compared to the UUC, performance evaluation and/or calibration adjustment of the UUC to identify or minimize errors is possible.

Our Electro-technical calibration services are equipped to calibrate almost every electrical parameter covering basic working level instruments like ammeter / voltmeter to Multifunction calibrators & 8½ digit multimeters.

Thermal Calibration Services

Calibrating instruments that measure temperature is crucial to the functioning of various industries, from healthcare to manufacturing. Fixed points are among the most accurate devices available for defining a temperature scale. Moreover, fixed point cells are designed to realize the liquid-solid equilibrium temperatures of certain high-purity metal elements. They are used in the calibration of thermometers at ITS-90 fixed points.

We have the capacity to calibrate SPRT/PRT using the primary method (fixed point cell). In addition, we also offer calibration services of various sensors, ovens, autoclaves, and chambers for temperature and humidity parameters, covering a range of -196 degree Celsius to 1200 degree Celsius.

Pressure Calibration Services

Pressure calibration refers to the comparison of the output of a device that measures pressure with that of another pressure-measuring device or standard. The process involves plumping the Device Under Test (DUT) to the standard device and generating a common degree of pressure in the measurement circuit.

We use fundamental pressure standards, such as piston gauges, with traceability through a national metrology institute. The procedures are conducted in our fully-equipped pressure calibration laboratory, which is optimized to produce the highest level of accuracy. Our scope of work includes calibrating all secondary / working level instruments like Dead Weight Testers (Gauge / Absolute / Vacuum), Pressure Calibrators, Test Gauges, and Pressure Transmitters / Gauges ranging from small pressures of only a few Pascal in value to high pressures up to 2000 bars.
