Vacuum Control Unit VC 900
Application: Rotary evaporation, Distillation, Multi-user vacuum systemEasy to use to control the vacuum applicationSeparate control unit with pressure sensors and two-step controlled valve to be placed independently from the operating unitVacuum controller can be operated with components from KNF and other producersPlease order the appropriate control cable for operating the N 920 G pump separately.
Vacuum Control Unit VCpro 601
Measures and displays vacuum pressure both graphically and digitally from 1100 to 1 mbar. Controlling the pressure can be done in real-time. The durable, chemically resistant sensor built into the VCpro 601 vacuum controller is a ceramic thick film hybrid. The sensor reading is gas independent and gives an absolute pressure.Precise vacuum control with timed ramp capabilityFully programmable modes to allow run repeatabilityIntuitive ICON-navigation of control screensConnectivity through LAN and RS232Built-in function for self-cleaning of diaphragm pumpSecurity levels for administrators and usersLog files on all pump activities for easy traceabilityHigh-Res display with dark and light screen modesDigital and analogue vacuum pressure displayAutomatic destillation controlCan be used with diaphragm or piston pumps from any manufacturerSuction / pressure connection: DN8 (6,35 mm ID) DN4 (3,2 mm ID)Inert Gas Port to Release Valve: DN4 (3,2 mm ID)
Vacuum Controller VACUU·SELECT
Fully equipped vacuum controller with capacitive, gas type-independent absolute pressure measurement using an alumina-ceramic diaphragm.
