Electrotechnical Metrology

Electrical measuring instruments have applications in all kinds of industries, from food and pharma to automotive and manufacturing. Hence, the calibration of these electrical instruments plays a significant role in ensuring safety and quality in these industries. It is also mandated by regulation for certain industries to have their instruments and devices calibrated at periodic intervals. Calibration ensures that the measurement values given by these devices are true to the value and hence ensure smooth operations. Calibration also guarantees the traceability of the measurements.

Our laboratory is climate controlled, with the temperature maintained between 252oC and 75% and the humidity between 45% and 75%. Our electro-technical calibration lab is equipped with state-of-the-art test benches for the lab standards. Master equipment with traceability to national or international standards is available for the calibration of instruments.
