Precision Test Gauge for 200 psi Systems

The Ashcroft 45-1082AS 02L is a new electronic test pressure gauge built for professionals who require high-accuracy measurement up to 200 psi. It features a 4 1/2 inch dial with a white mirror-band face that reduces parallax error during reading. The aluminium case provides durability while the glass lens protects the dial in workshop environments. Accuracy is rated at +/- 0.25 percent of span.

Upgrading from Lower-Accuracy Analog Gauges

This model replaces standard industrial gauges where tighter tolerance is required for calibration or quality-control tasks. The jump is worth it when your process demands quarter-percent accuracy rather than the broader one or two percent common on general-service instruments. It also supersedes gauges lacking a mirror band if parallax has been a source of reading inconsistency. The bottom-mounted male NPT connection suits existing panel cut-outs of 4.875 inches.

Verify Panel Cut-Out and Connection Compatibility

Before ordering, confirm your panel cut-out matches the 4.875 inch diameter required for this case. The process connection is a 1/4 inch male NPT thread located at the bottom; ensure your piping or test stand accepts this size and orientation. The gauge is not field fillable and carries no IP or NEMA rating, so it is not suited for wash-down or outdoor exposure. Bolt circle diameter is 5.375 inches if you are using the flange for surface mounting.

Questions about this item

What panel cut-out size does the 4 1/2 in gauge require?

The gauge needs a 4.875 in panel cut-out for flush mounting.

How do I connect the 1/4 in male NPT fitting without damaging the threads?

Apply PTFE tape to the male NPT threads and tighten by hand before using a wrench for the final turn; the bottom-mounted connection aligns vertically.

Does the glass lens or aluminium case need periodic servicing?

No field-fillable port is present, so the sealed unit requires no fluid top-up; simply wipe the glass lens and check the zero pointer against the mirror-band dial during routine calibration.
