General Overview

JNMI comprises 14 laboratory disseminated between primary and secondary level. We are concerned in providing an adequate measuring and calibration services via traceable calibrated references in both its primary and secondary level to satisfy the national and regional needs, thus our laboratory divisions can be summarized as follows:

• National Primary Laboratories , which comprise national measurement standards that are considered the most accurate measuring standards on the national level in the following fields:

• Electrical measurement such as measurement of voltage, current, resistance, capacitance, Inductance , frequency and time.

• Physical and mechanical measurement such as Temperature , Humidity, Dimension, Pressure, Mass, and Force.
   

• The secondary laboratories , which comprise a less accurate measuring standards, providing calibration services in the fields of the electrical, physical and mechanical measurement as well as Power , flow, volume, speed, luminance, and biomedical measurement equipment.
