VG502 Vacuum Gauge

The VG502 vacuum gauge is designed for vacuum measurements in medium and low vacuum (10^4 to 10^-1 Pa) ranges and for pressures up to 160 bar. The VG502 acquires and displays the signal from an external vacuum/pressure sensor (Pirani head, Active Pirani, and strain gauge). Compared with previous-generation vacuum gauges, the VG502 includes a serial RS485 interface for host computer connectivity, Wi-Fi communication, an automatic gas ballast option, digital I/O for remote start/stop and status indication, a back-lit LCD display with alphanumeric and analog readouts, a functional keyboard, and IP54 protection on the front panel.

The VG502 can work as a standalone instrument or as an integrated system with RecData TJ V software.
