Product details
product overview
The PTB220 series digital pressure gauge has the characteristics of pressure resistance and wide temperature resistance range. The A-grade pressure gauge is carefully adjusted and calibrated by a gravity tester. The B-class pressure gauge is calibrated according to electronic working standards. A single pressure gauge can have 1, 2, or 3 pressure sensors. The application of 2 or 3 pressure sensors provides reliable assurance for airports, weather stations, and pressure standards.
The PTB200 series pressure gauge uses Vaisala's BAROCAP silicon capacitive absolute pressure sensor to measure atmospheric pressure. The BAROCAP sensor has excellent characteristics such as no hysteresis, repeatability, temperature resistance, and long-term stability. All PTB220 pressure gauges come with a calibration certificate when they leave the factory.
