Test Gauges are highly precise and are used in laboratories, for industrial gauges calibration and other applications where accuracy and repeatability is of prime importance. The calibration is carried out with the help of highly accurate dead weight pressure standards in NABL Accredited Laboratory, traceable to National and International Standards.
Safety pattern gauges are used in the gas industry and are designed keeping in mind operator safety in case of a bourdon tube rupture and that no projectiles will blow out from the front of the gauge. Safety pattern construction comprises of a baffle wall, safety window and bigger blowout disc in the rear side of the case. For Oxygen and Acetylene service, safety pattern gauges must be used and are degreased before being supplied.
The capsule comprises of two diaphragms bonded at the circumference by means of Laser welding. Capsule Pressure gauges are used for measuring low / very low pressures and vacuum. The pressure medium needs to be gaseous. The calibration is carried out with the help of highly accurate standards which are traceable to National and International Standards.
