This manual introduces the PCA 300/PCA 301 series of chlorine analyzers, including preliminary examination, general description, mechanical dimensions, functional description, LED display, indicators and keyboard, specifications, operating instructions, initial preparation and installation, installation personnel, instrument location, hydraulic connections, installation of input filter, installation of pump tubes, electrical connections.
The Hanna Instruments PCA 300 and PCA 301 series are microprocessor-controlled, panel-mounted chlorine analyzers designed for continuous monitoring of free and total chlorine content in the 0 to 5 mg/L range. These instruments utilize the DPD Colorimetric method to measure chlorine concentration via a photometric system and display the results on a four-digit LED panel. The units feature alarm functions, user-selectable sampling periods, recorder outputs, and RS232 ports for data transmission to external computers.
| Measurement Range | 0 to 5 mg/L (ppm) |
|---|---|
| Output Voltage Levels | 0-10mV, 0-100mV, 0-1V |
| Current Output | 4-20 mA |
The analyzers monitor chlorine content in the 0 to 5 mg/L (ppm) range.
The instruments use the DPD Colorimetric method, mixing N, N-Diethyl-p-phenylenediamine indicator and a buffer with the sample.
With a sampling period of 5 minutes, reagents need to be replenished about once a month.
