2117HL Schematic
Thermo Scientific Orion 2117HL High Level Chloride Analyzer User Guide
The sample enters the Thermo Scientific Orion 2117HL chloride analyzer
and passes through the inlet valve, bypass/needle valve, inlet filter, pressure
regulator, flow meter and into the restrictor tubing. The sample then passes
through the flow cell manifold into the flow cell as air is introduced from
the air pump to ensure proper mixing and fast response. The sample passes
the chloride sensing electrode, reference electrode and ATC probe and then
flows into an atmospheric drain via the diverter valve.
