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
