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

Each unit has a membrane face with raised buttons and tactile

feedback for setup and operation. The high, low, and clear but-
