Vacuum gauge for industrial use

The Ashcroft 351009SWL02LVAC is an electronic vacuum gauge built for industrial measurement tasks. It covers a primary pressure range of 30 to 0 with a temperature span of -20 to 150 degrees Fahrenheit. The 304 stainless steel case and polycarbonate lens suit harsh environments where durability matters.

Simple NPT installation with venting choice

A 1/4 inch male NPT bottom connection threads directly into standard ports without adapters. The field-fillable design allows liquid dampening to be added on site if vibration resistance is needed later. Users must ensure the vent plug is set correctly: open for IP54 rating or closed for IP65 and NEMA 4 protection against dust and water ingress.

Steady accuracy under continuous load

Liquid-filled dampening and a +/- 1.5 percent accuracy spec keep readings stable during sustained vacuum cycles. The metallic case dissipates heat while the polycarbonate lens resists impact and chemical exposure. This gauge is not suited for applications that require digital output, data logging, or pressure ranges beyond the stated 30 to 0 scale.

Questions about this item

How can I confirm the gauge reads correctly after installation?

Apply a known vacuum source and verify the pointer settles within the +/- 1.5 percent accuracy band across the 30 to 0 range.

What comes in the box and what must I supply?

The gauge ships with a 304 stainless steel case, polycarbonate lens, 1/4 in male NPT bottom connection and liquid-filled vibration damping; you must provide thread sealant and any mounting hardware.

Which IP rating should I choose for my environment?

Select IP54 when the vent plug stays open for atmospheric reference, or IP65 and NEMA 4 when the plug is closed for wash-down protection.
