Digital Compound Gauge -14 to 10000 psi

The Fluke 700RG31 is a digital compound gauge built for technicians who measure both vacuum and positive pressure in one instrument. Its range spans -14 psi to 10000 psi with an accuracy of +/- 0.05 percent. The sensor uses a silicon substrate and the case is cast zinc aluminium rated IP67. It accepts clean dry non-corrosive gas or liquids and gases compatible with 316 stainless steel.

Replaces analogue compound gauges

Moving from a mechanical dial to this electronic gauge removes parallax error and adds a clear digital readout. The jump is worth it when you need documented accuracy of +/- 0.05 percent across the full -14 to 10000 psi span. The IP67 rating also protects the electronics in wet or dusty environments where a traditional gauge might fail.

Suits calibration labs and field service

This gauge suits calibration labs and field service engineers who need a single tool for vacuum and high-pressure work with media compatible with 316 stainless steel. It is not for applications involving flammable, toxic, explosive or oxidising media. Buyers who require a hazardous-location rating or a different pressure range should look at other instruments.

Questions about this item

What thread size and material does the 700RG31 use for mounting to a process line?

The gauge connects through a 1/4 in fitting and the sensor material is 316 stainless steel, so use a matching 1/4 in port rated for 316 SS.

How do I power up the 700RG31 and what is the common setup mistake?

Install the internal batteries, then zero the display at atmospheric pressure before applying any process pressure; skipping the zero step is the most frequent error.

What ongoing checks does the 700RG31 need to stay within its 0.05% accuracy spec?

Re-zero the gauge before each use, verify calibration annually against a traceable standard, and replace the batteries when the low-battery indicator appears.
