Ashcroft 2 1/2 in Compound Gauge

The Ashcroft 251009SW02LV/15# is an industrial compound gauge with a 2 1/2 in dial that reads vacuum from 30 to 0 and pressure from 0 to 15 psi. Its 304 stainless steel case and polycarbonate lens meet IP54 with the vent plug open and IP65 when the plug is closed. A 1/4 in male NPT bottom connection mounts directly to the process line. Accuracy is rated at +/- 1.0 percent of span.

Suited for vacuum and low-pressure monitoring

Technicians who need a single instrument to track both vacuum and positive pressure up to 15 psi will find this gauge appropriate. It is not suited for applications requiring pressure ranges above 15 psi or for installations that demand built-in liquid damping or vibration-resistant construction. Users needing a panel-mount or back-connected fitting should consider a different model.

+/- 1.0 percent accuracy defines suitability

The gauge delivers +/- 1.0 percent full-scale accuracy across the 30 to 0 to 15 psi range. That tolerance determines whether the instrument meets the calibration requirements of the specific test or process. If the application calls for tighter accuracy, this gauge will not satisfy the specification.

Questions about this item

Does the IP54 vented or IP65 closed rating keep the gauge cool and quiet during continuous use?

The gauge has no fan or active cooling; it relies on its 304 stainless steel case and polycarbonate lens to dissipate heat passively, and the mechanical movement produces no audible noise.

What process connection must my system already provide for this gauge to install?

Your system needs a female 1/4 in NPT port at the mounting point because the gauge has a male 1/4 in NPT bottom connection.

Will the +/- 1.0 percent accuracy hold if I keep using my existing 30 to 0 to 15 psi calibration equipment?

Yes, the gauge’s primary range is 30 to 0 to 15 psi with +/- 1.0 percent accuracy, so it matches the span of your current calibration standards.
