Pressure Gauge Calibration is an important part of measuring and maintaining the pressure levels in various industrial, agricultural and medical devices. The main purpose of pressure gauge calibration is to acquire a standard level of pressure that is below that of which the product can be safely utilized. It helps in determining the pressure of various components of these devices without making any change in their physical dimensions. This prevents faulty measurements from taking place as well as facilitates the use of the same in various applications. For this, certain steps are to be followed.

Before carrying out pressure gauge calibrations, certain high accuracy factors have to be determined for best results. The first factor that has to be considered is the type of device to be calibrated. All types of gauges can be calibrated using common methods, but for some special types of gauges high precision needs to be ensured. High pressure applications necessitate high accuracy high-resolution instruments such as multimeters, sensors, and special digital output signals with high frequency. Different tools used for high pressure gauges have different features. Some measure pressure very precisely, while others may give very high readings.
Some common types of high accuracy instruments include differential pressure gauges, high-frequency oscillators, ultrasonic sensors, and pressure gauge calibration equipment. High-quality instruments need to be expensive. High precision multimeters are generally made using high-quality materials and offer high precision performance. It is very important to choose the right type of multimeter for the application. A multimeter that is not sensitive enough to a specific value often gives incorrect results.
