Ashcroft 45-1082AS 02L 200 PSI Test Pressure Gauge

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.
