Page 5 - GENERAL DESCRIPTION
5 GENERAL DESCRIPTION The Hanna PCA 300 and PCA 301 series of Chlorine Ana- lyzers are microprocessor-controlled, process analyzers whichcontinuously monitor a sample stream for Chlorine content. The PCA 300 series monitor Free Chlorine and the PCA 301 series Total Chlorine in the 0 to 5 mg/L (ppm) ...

6 Two selectable chlorine level setpoints can be set by the op-erator: a proportional dosing setpoint and an alarm setpoint.Both setpoints control a SPDT relay. The proportional dosing setpoint analyzers is user-selectablewith a delta from 0.1 to 2.0 mg/L (ppm). The alarm level can be set by the use...
