Overview
The Ralston LC30 pressure / temperature gauge is the panel-mount, AC-powered version of the LC pressure / temperature gauge. It reads pressure from the back connection and temperature from an external probe with an M12 connector. For example, LC30-GA2M-TX125-00 is a 30 inHg vacuum / temperature gauge. Per Ralston, the LC30 shows high and low values on-screen, switches between engineering units or custom units, and includes FieldLab Desktop PC software. Pressure ranges vary by model.
