As pressure is an important process variable because of which it sets the critical conditions for boiling, chemical reactions, distillation etc and also many factories, metrological laboratories use this pressure calibrator equipment as this high accuracy equipment is used for calibrating industrial devices like pressure gauges and transmitters. The types of pressure calibrator are digital pressure calibrator are known for its accuracy and is designed for testing mechanical pressure gauges and pressure sensors. The most important factor of this pressure calibrator is that it lays more emphasis on speed as the patented pressure regulator is very much designed for testing mechanical pressure gauges.

The characteristics of these pressure calibrators are very interesting as these have user friendly menu screens which facilitate the set up of specific limits within the full scale capability of the instrument. Menus can be configured in different languages for the international use. The high speed pressure controller is equipped with a touch screen interface which makes calibration and testing sensor which are easy and quick. Another type of pressure calibrator is automated pressure calibrator known for establishing a new standard for its flexibility and also has two independent precision pressure regulating channels. In this type each channel would control pressure in an independent precision pressure which also has loop which contains two transducers as these transducers have an accuracy of about 0.01%.
