Piston pressure-vacuum gauge with equilibration liquid column

●Model Measuring range
YY0.4 -0.1~0.4MPa
YY0.7 -0.1~0.7MPa
●Characteristics:
★ Installed a thermometer on class 0.005 piston gauge in order to make temperature correct easily.
★ Be used for measuring zero pressure, negative pressure and positive pressure.
★ High sensitivity, high accuracy, wide range, and low decline speed of piston.
★ Piston and piston cylinder are made from WC hard metal alloy. Well wear resistance and long useful lifetime.
★ The working position of piston is monitored by displacement sensor and digital meter, which may be read more conveniently and accurately.
★ Be used for working primary standard or calibrating high precision instruments.
