T
he 56 Analyzer offers single or dual sensor input with an unrestricted choice of dual
measurement combinations. Measurements capabilities include pH/ORP, Resistivity/
Conductivity, % Concentration, Total Chlorine, Free Chlorine, Monochloramine, Dissolved
Oxygen, Dissolved Ozone, Turbidity, Pulse Flow, Temperature, and 4-20mA input.
The device includes two isolated inputs, nine local languages, four 4-20mA current outputs,
removable connectors for power and current outputs, and four solid plugs for closure of
openings. HART digital communications is included at no additional charge. Profibus digital
communications is optional.
