Industrial Vacuum Gauge

This Ashcroft 251009SWL02LVAC is a 2.5-inch dial vacuum gauge built for industrial and automotive testing. It measures vacuum from 30 inches of mercury to zero with a stated accuracy of ±1.5 percent. Technicians and engineers who need reliable low-pressure readings in the field will find it suited to routine diagnostics and system verification.

Stainless Case with IP54/IP65 Rating

The gauge case is made from 304 stainless steel and carries a polycarbonate lens. A 1/4-inch male NPT bottom connection allows direct mounting to test ports or manifolds. The case is field-fillable for liquid dampening and offers IP54 protection with the vent plug open or IP65 and NEMA 4 when the plug is closed, resisting dust and water ingress in harsh environments.

Liquid-Filled Vibration Resistance

The liquid-filled design damps needle vibration caused by pump pulsation or mechanical shock, keeping the pointer steady during normal operation. No dry dampening feature is fitted, so the fill fluid handles both vibration and lubrication. Power draw is not applicable for this mechanical instrument, and there are no fans or electronic components to generate noise.
