I am currently working in one National wise approved calibration lab. Here all type instruments are calibrating by Calibration Engineers. The calibrating instruments are like Vernier, Weighing scales, all type gauges, Thermometer, Temperature controller, Micrometer, Electrical Instrument etc.. In comparing India level we are only having the National Accelerated for all type of gauges and oftenely used intruments like Micrometer, Weighing scales and all. After calibrating the instrument we are submit the approved NABL report for that instrument.
