Calibration Laboratory

Kharafi National’s Calibration Laboratories are in-house centers of excellence for the calibration of all types of measuring and monitoring devices used on projects. Each operational area in Kuwait, the UAE and Egypt has its own calibration laboratory to ensure that all monitoring and measuring devices are fit for use and are maintained to suitably accurate and acceptable standards.

At Kharafi National, the use of only properly calibrated devices is of the utmost importance. It is corporate policy that all measuring and monitoring devices needed on projects are purchased, owned, maintained and regularly calibrated by Calibration Laboratories. The projects take monitoring and measuring devices from their local laboratory, use them as required, and then return them to the laboratory for recalibration on the due dates.

Calibration services

The laboratories are equipped with master calibrators, calibration software and supporting reference standards. The master calibrators are traceable to national and international standards. The laboratories have fully trained engineers, technicians and support staff to ensure a high quality of service and the range of calibration equipment is truly comprehensive.

The laboratories have over 7,700 different types of monitoring and measuring devices to support projects.

Besides manual calibration procedures, the laboratories have more than 1,500 Fluke MET/CAL procedures for the calibration of different types of instruments.

The laboratory in Kuwait has an Infrared Thermal Imaging camera that is used for predictive maintenance

The laboratories can undertake the calibration of instruments on site if required. They can also make arrangements for third party calibrations of specialized instruments if the required resources are not available in-house.

The laboratories also undertake various on-site services other than the calibration of instruments on behalf of clients.
