1.3 ORDERING INFORMATION

The Model 54eA Microprocessor Analyzer measures dissolved oxygen, free chlorine, total chlorine, ozone, and pH. pH is available for free chlorine only. The analyzer has an on-board pressure sensor for automatic air calibration of oxygen sensors. Amperometric measurements are fully compensated for changes in membrane permeability with temperature. Free chlorine is corrected for pH. Standard features include a three-line back-lit display, dual isolated outputs, and three programmable alarm relays. HART communications and PID and TPC control are optional.
