Who we are

From the laboratory floor to your screen

PTR India started with a simple observation: most of what a calibration engineer, lab technician or quality manager needs to know is learnt on the job, scattered across standards, procedures and the experience of senior colleagues. We bring that knowledge together in one place, in plain language, with visuals that make it stick.

Everything published here is written and reviewed by people who calibrate instruments, prepare for NABL assessments and run quality systems every day. Our content follows ISO/IEC 17025:2017, NABL guidelines and the GUM approach to measurement uncertainty, and is kept current as the standards evolve.
