Gas connection:
The gas supply lines between the device and the gas supply system are connected using the supplied
connecting hoses. CO

All process gases must be supplied to the device at a fixed pressure that has been preset within a range of
0.8 to 1.0 bar (11.6 to 14.5 psi) and must remain unchanged.
Before the gases are fed into the workspace, they flow through a gas inlet filter with a separation rate of
99.998 % for a particle size of 0.3 µm (HEPA-filter quality).
The illustration shows the optional combined gas connection without the optional gas monitoring
system.

The interface port accepts various customer-supplied external measurement devices with 4-20 mA
inputs - for example, the Thermo Scientific Smart-Vue Wireless Monitoring System (not supplied).
