Calibration of equipment is done to determine efficiency and accuracy of measuring is a comparison method whereby test gauge readings are compared with standard readings both connected to the some pressure source.

To improve the quality of the calibration and have the results accepted by outside organizations it is desirable for the calibration and subsequent measurements to be “traceable” to the internationally defined measurements units.


Our Labs are accredited by Kenya National Accreditation Service (KENAS) after satisfying the requirements of ISO/IEC 17025(2005). (General Requirements for the competence of testing and calibration laboratories).Our scope of accreditation is calibration in the fields of Temperature, volume and Pressure.etc. Our Technicians have a wide knowledge and experience in calibration of Tanks, Thermometry equipment, industrial Pressure Gauges (bourdon tubes), Volume, and Non-Destructive Testing (NDT).

All our calibration standards are traceable to Kenya Bureau of Standards (KEBS). We are accredited by Kenya National Accreditation Services (KENAS).

Our long experience of all types of equipment enables us to offer a comprehensive calibration service and maintenance service in all environments. Our policy is to make all efforts to keep your equipment in full working order and our good relationship with all major manufacturers and suppliers enables us to source parts at competitive prices.

NSQI scope of calibration capability TRACEABILITY to International Standards (SI UNITS) is offered through Kenya Bureau of Standards (KEBS).

Please note that we prefer to undertake our testing/calibration assignments on site in order to minimize disruptions to our clients’ operations.

Calibration: Pressure

Recommended schedule for pressure calibration is as follows:

1 Industrial Pressure Gauge (bourdon tube) 1 year
2 Test Pressure Gauge 1 year
3  All types of Tyre Pressure gauges 6 Months
4 (blood Pressure gauges) 6 Months
5 Combination Gauges (normal Pressure) 6 Months
6 Force Test Gauges (bourdon tube) 6 Months
7 Gas Regulators for welding &allied equipment 1 year

Calibration: Weighing scale.

This includes calibration of weighing scales, weighing instruments, weighing balances. Weighing scales are widely used in industry for various measurements. Some weighing instruments are small laboratory instruments measuring a few grams and need to be very accurate. Industrial weighing instruments are very large ones that measure, for example, mass of load. As with any measurement instruments, weighing instruments should also be calibrated regularly to assure that they are measuring correctly and accurately. A proper metrologically traceable calibration is the only way to know how accurately weighing instruments are measuring.

Many weighing instruments are used for legal measurements or measurements used as basis for monetary transfer and these are part of a legal or statutory verification program based on legislation
