We offer calibration facilities for every type of gauge ordered from us. The gauges are checked in a controlled enviroment at 20 ±1°C and relative humidity of 50 ±5 RH using instruments directly traceable to International Standards. For this traceability all of the major instruments are regularly calibrated by "National Physical Laboratory (NPL)".

  Heat treatment is made in controlled atmosphere electrical furnances which offer a very precise temperature control. The furnances are fitted with electronic controllers along with data logger for recording the cycle parameters. The heat treatment cycle includes stress reliving, pre-heating, austenitizing, oil quenching and double tempering.
The heat treatment process is periodically validated to achieve consistent and good quality microstructure.

  The hardness of gauges is 60-62 HRC.
