Purpose-built vacuum gauge

The Ashcroft 302074SD02L is a digital test vacuum gauge designed for technicians who need accurate negative-pressure readings from -30 to 0 psi. Its 3 in dial and stainless-steel case suit field service, calibration labs and industrial maintenance where a rugged, portable instrument is required.

Sustained-load behaviour

Rated IP65, the gauge resists dust and water jets during extended use in harsh environments. The diaphragm sensor and 316 stainless-steel socket maintain the stated ±0.25 percent accuracy over long test cycles, while two AA batteries power the electronic display without mains dependency.

Deciding specification

The measurement range of -30 to 0 psi determines whether this gauge matches the vacuum level you must verify; if your application requires positive pressure or a deeper vacuum, a different instrument is needed.
