The Welch Model Vacuum Controll-Box VCB 601 - CV measures and displays vacuum pressure both graphically and digitally. The vacuum pressure can be controlled from 1100-1 mbar (825 to 0.75 Torr). Controlling the pressure can be done in real-time.
In addition, a timed ramp function allowing raising & lowering pressure is built in for applications such as distillation and vacuum drying. Full flexibility and repeatability is achieved easily via a programmable mode with pressure over time defined by the user.
The durable, chemically resistant sensor is built into the vacuum Controll-Box VCB 601- CV is a ceramic thick film hybrid. The sensor reading is gas independent and gives an absolution pressure.
