Calibration Services

Calibration is the process of configuring an equipment, to provide a result within an acceptable range. Calibrating equipment’s regularly is important, for maintaining the quality, and the accuracy of the instruments. Our services extend to every industry, where a machine or equipment, requires calibration. Equipment calibration is the primary step taken to maintain the accuracy of the instruments. The goal of calibration is to minimise any measurement uncertainty by ensuring the accuracy of test equipment. Therefore a routine calibration check is highly essential. We offer high-performance measurement in calibration & Inspection services and we are committed to helping you maintain that performance for years to come.

Insights into Lawkim Calibration Services:

Electro Technical

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.

Radio Frequency Calibration

Radio frequency (RF) is the rate of oscillation which corresponds to the actual frequency of radio waves, and the alternating currents which carry radio signals. There are many industries that benefit from accurate radio frequency. The usual applications are the carrier wave frequency to small tolerance in broadcast transmitters and other wireless communications. Even the telecom networks and the metrology department use the calibrating frequency generated device.

Our accredited facility is equipped to calibrate RF instruments up to 22 GHz at in-house as well as customer premises.

Pressure calibration is the comparison of the output of a device used to measure pressure with that of another pressure measurement device, or pressure measurement standard. This usually involves plumbing the device under test (DUT) to the standard device and generating a common pressure in the measurement circuit.

In our pressure calibration laboratory, we use fundamental pressure standards, such as piston gauges, with traceability through a national metrology institute. We can calibrate all secondary/ working level instruments such as Dead Weight Testers (Gauge/ Absolute/ Vacuum), Pressure calibrators, Test Gauges and Pressure Transmitters/ Gauges ranging from small pressures of only a few Pascal up to high pressures up to 2000 bar.

Bio Medical Calibration

Biomedical calibration is the process of configuring the measurement and the accuracy of the medical device or the medical system used in Hospitals. This field intends to offer advance healthcare treatment, including diagnosis, monitoring and therapy.

The biomedical calibration measurements, is important because they establish whether the medical devices are appropriate, according to the international standards or not. The calibration also helps to minimise misdiagnosis caused by poorly calibrated machine. It is very important to configure hospital systems, according to the standard calibration because these machines need to be absolutely accurate since it is a matter of life and death.
