ERTL (South) has comprehensive facilities for calibration of majority of the Test & Measuring equipment used by the industry. Facilities are available for the calibration of electrical parameters. The accuracy levels of the standards used are traceable to the National Physical Laboratory, New Delhi. The Laboratory is accredited by National Accreditation Board for Testing and Calibration Laboratories (NABL),
In addition to providing calibration services at our laboratory, on-site calibration services are also undertaken facilitating calibration of equipment at the customer’s premises.
