Model JS Digital Pressure Gauge With Output DESCRIPTION The Model JS digital pressure test gauge with 0.2 % full scale output. The Model JSX provides a 0 Vdc to 5 Vdc output with accuracy uses transducer technology and a stainless steel dia- two programmable limits and relays for process control or alarm phragm for high over pressure protection.
