Industrial Compound Gauge

The Ashcroft 251009 compound gauge measures pressure and vacuum from 30 to 0 to 30 with a stated accuracy of +/- 1.0 percent. It is built for technicians and plant operators who need a single instrument to monitor both positive and negative pressure ranges in industrial processes.

304 Stainless Steel Case with IP54 and IP65 Ratings

The gauge case is constructed from 304 stainless steel and carries a metallic finish. A 1/4 inch NPT male bottom connection suits standard panel or pipe mounting. The polycarbonate lens protects the dial. With the plug vented the unit meets IP54; with the plug closed it meets IP65 and NEMA 4, allowing use in wash-down or dusty environments.

Field-Fillable Design Not Included

This model is not field fillable and has no dry dampening or vibration resistance features. Buyers who require liquid filling for pulsation damping or who need a gauge rated for severe vibration should select a different configuration. The fixed bottom connection also means the gauge cannot be rotated after installation.

Questions about this item

What does the 1/4 NPT bottom connection mean for installation?

The gauge has a male 1/4 inch NPT thread on the bottom for direct mounting into a female NPT port; use PTFE tape on the threads and tighten with a wrench on the hex flats only.

Will the 2 1/2 inch dial and 304 stainless steel case fit my panel cutout?

The nominal dial size is 2 1/2 inches with a 304 stainless steel case designed for bottom stem mounting; verify your panel cutout matches the manufacturer's outline drawing before cutting.

How do I achieve the IP65 and NEMA 4 ratings on this gauge?

Keep the vent plug fully closed during operation; the IP54 rating applies only when the plug is vented, while IP65 and NEMA 4 require the plug to remain sealed.
