Product Description

The PCA320 Chlorine, pH, ORP, and Temperature Analyzer is a microprocessor-controlled process analyzer designed for continuous monitoring and control of key water quality parameters. With its advanced functionality, the PCA320 measures free and total chlorine, pH, ORP, and temperature in real time, enabling efficient process management in drinking water, wastewater, pool, and industrial HVAC applications.

This robust analyzer features a molded fiberglass polyester enclosure built to NEMA-4X standards, protecting the electronics in harsh environments. Configurable analog output signals (0-10 mV, 0-100 mV, 0-1 V, 4–20 mA, and 0–20 mA) provide seamless integration with process control systems. User-friendly 4-line by 20-character LCD supports English, Italian, Portuguese, and Spanish for ease of use by operators worldwide.

  • Chlorine measurement range of 0.00–5.00 mg/L with accuracy ±8% or ±0.05 mg/L.
  • Automatic one- or two-point pH calibration and selectable dosing setpoints for both pH and chlorine control.
  • Alarm relay (SPDT contact, 5A/230V) and proportional dosing relay for reliable process automation.
  • RS485 connectivity enables integration with industrial control and SCADA systems.
  • Extensive logging capacity with up to 3500 log records for compliance and troubleshooting.
  • Sample flow rate of 100–300 mL/min and inlet sample pressure of 0.07 to 4 bar (external regulator required above 4 bar).
  • Molded enclosure with transparent Lexan window ensures both durability and visibility.

This analyzer is ideal for industrial, municipal, laboratory, pool/spa, and water treatment environments. The package contains the analyzer itself (without reagents), as well as all necessary fittings and accessories for rapid commissioning.
