These digital pressure and vacuum gauges are an ideal alternative to your mechanical gauges! These gauges offer high accuracy plus the convenience of a digital display. The semiconductor sensing element measures pressure with ±0.25% or ±0.5% accuracy (depending on the range), and lasts for millions of cycles. These gauges come standard with Zero-Reset, Backlight, and Auto-Shutoff to help prolong battery life. Peak hold is standard on all pressure units.

As an option, some models can also come with a 4/20mA transmitter and NPN limit switch. These units are line powered with 8-30VDC.
