System unit

The QC8500 Series 2 analyzer can be expanded with modular channels and daisy-chain

connections.

Heater controller, valve controller and leak detector signals share one ribbon cable. The

controller cable and power cable connections are made from the new channel to the

adjacent channel. Fiber optic and detector connections are made directly to the

System Unit.

before connecting or disconnecting channels.
