The ROOTS Metrology is the premier Calibration and Testing Laboratory in the field of Physical sciences.

ROOTS Metrology has been playing in the league of exceptional Calibration laboratories certified by NABL for more than “Ten” years.

As a premier calibration laboratory, it is equipped with precision calibration equipments.

The Metrology division provides calibration and measurement services to a large number of customers on Mass, Mechanical, Electrical, Pressure, Thermal, Vacuum and Torque. These services all conform to international standards, and the level of technical excellences provided by the laboratory is reflected in to accreditation the laboratory received from National Accreditation Board for Testing and calibration laboratory as per ISO/IEC 17025 : 2017 and Scope CC 2201.


The laboratory has been equipped with a highly sophisticated air-conditioning environment to achieve the required humidity and temperature conditions acceptable by International standards.

The temperature and humidity condition in each area can be controlled to the desired level during calibration. The laboratory is maintained at humidity 50±10% and varying temperature condition according to requirements since stability of the room temperature is highly important for high accuracy of measurements.

In addition to the above, Luminance, Air velocity, Noise level and Vibration level are also maintained to acceptable international level.
