Our Industrial Gas Pressure Gauge is a precision instrument designed specifically for monitoring gaseous media, from compressed air systems to critical safety equipment. Also known as a gas pressure meter or gas manometer, this robust device provides accurate, at-a-glance pressure readings essential for system efficiency, preventive maintenance, and—most importantly—safety verification, especially in fire extinguisher applications.

Gas-Specific Calibration: Engineered and calibrated for accurate measurement of air, inert gases, and other common gaseous media, ensuring reliable performance as a dedicated gas pressure meter.
Critical Safety Tool: Plays a vital role in safety systems. Its widespread use in fire extinguishers allows for instant visual verification of charge status. A needle in the green "GOOD" zone confirms the unit is operational and ready for emergency use.
Durable & Leak-Resistant: Built with seals and materials compatible with various gases to prevent leakage and ensure long-term integrity. Ideal as an air pressure gauge meter on compressors, receivers, and pneumatic tools.
High-Visibility Dial: Often features color-coded zones (e.g., red/yellow/green) for immediate status assessment, even from a distance during safety inspections.
Broad Application Range: From industrial air lines and natural gas monitoring to medical gas systems and laboratory setups, this versatile gas manometer is a fundamental component.

| Common Pressure Ranges | 0-300 psi, 0-25 bar (or dual-scale) for air/industrial use; Specific low ranges (e.g., 0-500 psi) for fire extinguishers. |
| Connection | Radial (Bottom) or Axial, typically with brass or stainless steel stem |
| Case Material | Polished Brass, Chrome-Plated Steel, or Stainless Steel |
| Window | High-Strength Plastic or Safety Glass |
| Dial | White with color zones; may include "FULL/REFILL" markings |
The gas pressure gauge is the primary visual indicator on a stored-pressure fire extinguisher (like ABC dry chemical or CO2 types).
Function: It measures the pressure of the expellant gas (typically nitrogen) inside the extinguisher.
Safety Indicator: The gauge clearly shows if the pressure is within the operable range (green zone), undercharged (needle in the lower red/white), or overcharged (needle in the upper red). This is a non-negotiable part of monthly safety inspections.
Compliance: Regular checks of the gas manometer reading are mandated by fire safety codes (like NFPA 10) to ensure emergency readiness.

Safety & Compliance: Fire extinguisher charge verification (primary application), medical oxygen tank monitoring.
Industrial Air Systems: Air pressure gauge meter for compressors, receiver tanks, pneumatic control panels, and tool lines.
Process Industries: Monitoring natural gas, propane, nitrogen, and other process gas lines.
HVAC/R: Checking refrigerant gas pressures during servicing.
Laboratory & Research: Precise gas pressure measurement in experimental setups.
Selecting the correct range, connection, and dial marking is crucial for your specific gas and application.
