A 4.5-in. Ashcroft digital pressure gauge, part of the Digigauge family, features easy battery replacement. The gauge comes apart with a quick twist of the front ring, and once the batteries are installed, the gauge can be hand-tightened to fit back in position. No tools are required. It comes with a standard thermoplastic case and cam lock ring or with an optional aluminum case and threaded ring. Both the cam lock and threaded ring rotate counterclockwise for removal. Additional features include an extra-large display, IP65 weatherproof case, and 0.25% terminal point accuracy.
