50mm Dial Black Steel Case Brass Internals -30mmHg Wholesale Vacuum
Low Pressure Gauge
Description
Low-pressure gauges have a bellows or a diaphragm sensor for
sensitive low-pressure readings. Diaphragm-sensor gauge
applications include gas burners, vacuum ovens, and suction
regulators/respirators. Bellows gauges are for applications usually
found in oil, gas, chemical, and water/wastewater pressure control
environments. Typical media applications include natural gas
pressure, air flow indications, and lead detection.
Applications
Low pressure gauge for applications in a controlled environment
Ideal for measuring pressure, vacuum in medical, environmental, and
laboratory applications for content and filter monitoring
For gaseous, dry and non-aggresive media
Special features
Front zero adjustment
Special connections on request
Scale ranges from 0/10 InWC (25 mbar)
