This instruction manual introduces the features of the PCA 310, PCA 320, PCA 330 chlorine, pH, temperature and ORP analyzers.
This instruction manual covers the Hanna Instruments PCA 310, PCA 320, and PCA 330 series of microprocessor-controlled process analyzers. These devices continuously monitor sample streams for free or total chlorine content using the DPD Colorimetric method, as well as pH, temperature, and ORP values depending on the specific model selected.
The manual provides detailed guidance on preliminary examination, installation procedures including hydraulic and electrical connections, startup steps, and user interface navigation. It includes comprehensive instructions for programming settings such as measurement parameters, alarm levels, analog outputs (4-20mA), and serial communication via RS485 or GSM. Additionally, it outlines calibration procedures for the measuring cells and maintenance tasks like electrode conditioning and pump tubing replacement.
| Measurement Range (Free/Total Chlorine) | 0 to 5 mg/L |
|---|---|
| pH Measurement Range | 0 to 14 pH |
| Temperature Measurement Range | 5 to 75°C |
| Sampling Period | Selectable (example: 5 minutes) |
| Analog Output | 4-20mA or 0-20 mA |
It mixes N, N-Diethyl-p-phenylenediamine indicator and a buffer with the sample to form a magenta color proportional to chlorine concentration.
With a sampling period of 5 minutes, reagents typically need to be replenished about once a month.
The code '1' indicates a Chlorine analyzer, '2' adds pH and Temperature, and '3' adds ORP.
No, they are not designed for use with samples that are inflammable or explosive in nature.
