Description:

With the development of the domestic metrology industry, the original vacuum piston pressure gauges lubricated with oil in gas media have gradually withdrawn from the historical stage, and gas piston pressure gauges have taken their place. Pure gas piston pressure gauges feature stable and reliable pressure performance, which significantly improves the sensitivity and accuracy of piston pressure gauges and provides an ideal standard instrument for high-precision metrology.

Features:

• The piston system is made of tungsten carbide, featuring wear resistance, a small temperature drift coefficient, and a long service life.
• The pressure range can be optionally selected within -100kPa~600kPa.
• Complies with JJG1086-2013 "Verification Regulation of Gas Piston Pressure Gauge", different from traditional oil-lubricated gas piston pressure gauges.
• The valve adopts a unique design, making pressure regulation convenient.
• The pressure interface is a quick-connect interface, ensuring convenience and efficiency.
• An optional digital indication system for temperature, pressure and descent is available, which is convenient and efficient.
• Measuring range: The nominal measuring range is consistent with the actual measuring range. Positive and negative pressure switching is convenient and quick. The piston system can be easily taken out for inspection (no need to carry the heavy main machine). It can be used as a verification piston pressure gauge for transmission and also for high-precision testing. It can be equipped with kg weights and MPa weights.
• The weights adopt a basket structure with a low center of gravity and excellent stability.
• The pressurization system is advanced, lightweight and durable.
• Each unit is provided with a "Verification Certificate" issued by the Northwest Institute of Metrology and Testing.
