Industrial Vacuum Gauge

The Zoro Select 18C739 is an electronic vacuum gauge built for industrial process monitoring. It measures pressure with a stated accuracy of +/-1.0 percent and suits technicians who need a reliable instrument for non-explosive gases or liquids that do not crystallise or corrode copper alloy.

Stainless Steel Case and Acrylic Lens

The gauge case is made from stainless steel while the lens uses acrylic. A copper alloy sensor and HPb59-1 socket handle compatible media, and the 1/4 inch male NPT bottom connection allows direct mounting into existing ports without extra adapters.

Bottom Mount Installation

The 1/4 inch male NPT bottom connection threads straight into a matching port, so fitting requires only standard thread sealant and a wrench on the hex. Errors usually come from using the gauge with media that crystallises or attacks copper alloy, or from applying pressure beyond the calibrated range.

Questions about this item

How often should the copper-alloy sensor and socket be checked for corrosion with compatible non-crystallising media?

The sensor and socket are copper alloy HPb59-1 and the gauge is rated for non-explosive gas or liquid that does not crystallise or corrode copper alloy, so periodic visual inspection of wetted parts is the only maintenance indicated.

What accuracy limit applies when the gauge is used continuously at full scale?

The stated accuracy is ±1.0 percent of reading, which remains the governing limit during sustained operation.

Does the stainless-steel case and acrylic lens run hot or make noise during all-day use?

The gauge is a mechanical dial instrument with no powered components, so it generates no heat and produces no audible noise in continuous service.
