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.
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.
Type of measuring and monitoring devices
The laboratories operate using leading master instruments in accordance with ISO 9001:2008 and ISO 10012:2003 international standards, and provide calibration and maintenance services for the following groups of instruments:

|Infrared Thermal Imaging|
Calibration Laboratories has acquired a state-of-the-art thermal imaging camera FLIR ThermaCAM P60, an advance tool in predictive and preventive maintenance. Infrared thermography is non-contact (remote sensing), two dimensional and real time.
Trained and certified engineers and technicians are available for onsite inspections, analysis and report issuance for predictive or preventive maintenance and troubleshooting in numerous applications. Calibration Laboratories offers onsite services in the following areas among others:
|High voltage equipment such as breakers, bus bars, transformers for hot connections, load imbalances, etc|
|Finding hidden problems in thousands of connections and terminations in control and low voltage panels|
|Motor windings, shafts and bearings|
|Over-heated conductors on printed circuits boards|
|Building cooling and heat losses|
|HVAC unit problems|
|Flange leaking in pressurized tanks and pipe lines|
|Pump bearing, coupling misalignments|
|Tank sediment and sediment along the lengths of pipes|
|Valve conditions in the petrochemical industry, etc|
|Insulation defects, sediment in pipelines|
|Fluid flow problems|
For newly installed or repaired equipment Calibration Laboratories can collect base-line data (ideal working conditions) and then regularly monitor the condition of the equipment as part of predictive or preventive maintenance to avoid break-downs and loss of production.
Calibration Laboratories ensure client satisfaction by offering services with a high degree of technical skill at competitive prices.
The laboratories offer instrumentation support either on their own premises or on-site, whichever suits client requirements. These services are currently provided in the following sectors:
|The laboratories’ on-site measurement services include a wide variety of tests:|
