Ashcroft 452074 Digital Pressure Gauge

The Ashcroft 452074 is a digital test pressure gauge built for technicians who need accurate readings on pressure-washer systems. It measures from 0 to 300 psi with an accuracy of +/- .25 percent and shows results on a 4 1/2 in display. The case is thermoplastic with a polyester lens and carries an IP65 rating for dust and water protection. Power comes from two C batteries.

Upgrade From Analog Gauges

This gauge replaces analogue dials that can be hard to read in bright light or awkward angles. The digital display removes parallax error and lets you switch between bar, ft wc, in Hg, kg/sq cm, kPa, mBar, Mpa and psi without extra tools. The jump is worth it when you need repeatable, documented readings for maintenance logs or calibration records. The diaphragm sensor and 316 stainless steel socket resist corrosion from detergents and harsh water.

Check Connection And Power Before Ordering

Verify that your equipment uses a male NPT process connection at the bottom port before purchasing. Ensure you have two C batteries available for operation, as they are not included. Confirm the 4 1/2 in case diameter fits your mounting panel or test rig. The gauge is not rated for hazardous locations, so do not install it in classified explosive atmospheres.
