Ashcroft 45-1082AS 02L 100 PSI Test Pressure Gauge

SKU CH-HX7T-1ZENW

Test pressure gauge with 4 1/2 inch dial measures 0 to 100 psi at ±0.25% accuracy

  • TypeElectronic
  • +/-0.25 % accuracy delivers laboratory-grade readings
  • 0–100 psi range covers common test pressures
  • 4 1/2 in dial with mirror band eases precise alignment
  • 1/4 in NPT male connection fits standard ports
  • Aluminum case with glass lens resists workshop wear

Precision Test Instrument

The Ashcroft 45-1082AS 02L is a 4 1/2 inch dial test pressure gauge calibrated for a 0 to 100 psi range. It delivers an accuracy of +/- 0.25 percent, making it suitable for calibration labs and critical process verification. The white dial features a mirror band to eliminate parallax reading errors. Its aluminum case and glass lens provide durability for bench or panel use.

Target Users and Limits

This gauge suits technicians who require traceable accuracy for pressure testing and instrument calibration. The 1/4 inch male NPT bottom connection fits standard test ports without adapters. It is not field fillable, so users needing liquid damping for vibration must select a different model. Buyers requiring an IP or NEMA environmental rating should look elsewhere as this unit carries none.

Sustained Load Behavior

Under continuous pressure at the top of its 100 psi range, the Bourdon tube maintains its calibrated accuracy without drift. The solid front aluminum case with blow-out back protects the operator if the tube fails during extended tests. The glass lens resists clouding from prolonged exposure to process fluids. Panel mounting via the 4.875 inch cut-out and 5.375 inch bolt circle ensures a secure, vibration-resistant installation for long-term service.

Questions about this item

What NPT thread size must my test port have to accept the 1/4 in process connection on this Ashcroft gauge?

The gauge uses a 1/4 in male NPT connection, so the mating port must be a 1/4 in female NPT thread.

Will the 4 1/2 in dial fit the 4.875 in panel cut-out I already have in my test panel?

Yes, the gauge is designed for a 4.875 in panel cut-out and uses a 5.375 in bolt circle for mounting.

How do I verify the gauge is reading within its +/- 0.25 percent accuracy after installation?

Apply a calibrated pressure source at several points across the 0 to 100 psi range and confirm each reading stays within 0.25 psi of the reference value.
