Gas Pressure Gauges
Use these gauges with pumps, filters, regulators, and in process lines to monitor the pressure of compressed gas. Mount them with the dial face upright. Gauges for use with acetylene can also be used in welding applications.
Gauges with brass case are cleaned to meet ASME B40.1, Level IV for oxygen service.
Gauges with 304 stainless steel case are cleaned and bagged to meet ASME B40.1, Level IV for oxygen service.

Panel-Mount Ultra-High-Pressure-Regulating Valves for Air and Inert Gas
- For Use With: Air, Nitrogen, Argon, Helium
- Temperature Range: -40° to 165° F
These valves are rated for inlet pressures up to 6,000 psi. They automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure. Adjust the outlet pressure within the range. Threads below the adjustment knob and an included mounting bracket let you install these valves in instrument panels. They have two gauge ports. An internal strainer traps debris.

Remote-Reading Tension Force Gauges
Safely view your tension force measurements on a handheld receiver up to 450 ft. away when moving bulk material with cranes and hoists. These gauges are also called dynamometers and crane scales. Made of steel, they’re durable enough to briefly hold heavy loads up to 500% of their capacity. But, they will no longer take measurements if the load exceeds 200%. Warning lights will flash first when your load exceeds capacity, then again when it reaches 133% capacity. To prevent overloads, the peak-hold setting displays the highest measurement. The tare function lets you reset the gauge to zero after attaching a container to weigh only the material inside. These gauges include a calibration certificate traceable to NIST that states they’ve passed a test for accuracy. They also meet IEC and ASME safety and fatigue standards.
Because their indicators and load cells are IP rated, these gauges stand up to washdowns and brief submersion common to food and chemical plants. They’re also safe to use outdoors since they’re NEMA rated to seal out weather.
These gauges come with two shackles that work with other lifting fittings, such as clevis hooks. The included batteries power their load cells for up to 2,000 hours.
