4.1 Functional principle

The Vacuum Controller V-850 and V-855 can be universally used for the display, adjustment and

control of vacuum. The integrated aeration valve and the precision pressure sensor are resistant to

chemicals making the Vacuum Controller a compact unit suitable for numerous applications in the

Lab. When using the vacuum controller with a Vacuum Pump V-700 or V-710 the new speed control

feature allows a hysteresis-free vacuum control with a low noise level.
