Measuring gas transfer
A heated gas transfer line is used to transfer the measuring gas. It connects the combus-
tion system of the basic module with the sulfuric acid container in the detection module.
The hose of the gas transfer line is connected to the sulfuric acid container connection
with a banjo bolt with a conical nipple. The other end of the gas transfer line is con-
nected to the auto-protection valve assembly in the basic device.

The measuring gas hose is connected directly to the combined electrode with the
"sensitive" and "high concentration" measuring cells.
