Series ZSE30A is a high-precision, 2-color display digital pressure switch for vacuum. It has raised rubber button controls that are clearly set apart, simple to operate and soft to the touch. Plug in type connectors take the burden out of wiring work and maintenance. Four different display settings are available. Settings can be copied to up to 10 slave sensors at once? , Possible to check
