Mechanical Calibration

JS Civil Lab Solutions supplies mechanical calibration equipment and reference standards for laboratories that calibrate or verify testing machines across India. The range includes proving rings in compression and tension (Class-1), certified dead weights, calibration reference bars for UPV instruments, plunger dial gauges, digital vernier calipers, micrometers, feeler gauges and precision weighing balances. All reference standards are supplied with NABL-traceable calibration certificates, supporting ISO/IEC 17025 accredited laboratories and in-house verification programmes. We help NABL labs build their calibration scope with correctly classed reference instruments, and support periodic recalibration through our partner network. Contact our technical team for guidance on proving ring capacity selection, dial gauge accuracy classes or complete CTM verification kits — with pan-India delivery and documentation support.
