PC2000 belongs to Chemtrol PC series water chemistry controller. It integrates multi-parameter measurement for pH, ORP, conductivity, TDS and water temperature. Powered by universal AC 100~240V, 50/60Hz. Equipped with backlit LCD display and membrane keypad for parameter setting, calibration and alarm configuration.

This controller has built-in relay outputs for automatic chemical dosing pump control, two isolated 4-20mA retransmission signals for remote SCADA system. RS485 digital communication supports data upload. It has probe fault diagnosis function to detect sensor aging or cable breakage automatically. Nonvolatile memory retains calibration data and setpoints after power loss. Panel mounting design with front panel IP65 protection, rear housing IP20. LED alarm indicators notify abnormal pH, ORP and sensor failure for fast on-site troubleshooting. Operating temperature range 0~50℃.

PC2000 is discontinued legacy water treatment spare part. Many old circulating water and pool water systems still adopt this controller. When the original unit fails, replacing it with identical PC2000 can reuse existing sensors, dosing wiring and original control setpoints. Technicians install the controller, calibrate pH/ORP probes, test relay dosing output and analog signal transmission, so the water quality monitoring and chemical dosing system resumes operation and reduces downtime.

Before shipment, every PC2000 undergoes comprehensive functional inspection including power-on self-test, display and keypad test, pH/ORP signal simulation test, relay action and 4-20mA output verification. All products come with 12-month warranty. Our automation technical team provides remote support for installation, probe calibration, parameter setup and fault diagnosis. Fast global shipping available for urgent maintenance orders.

For automation maintenance engineers and system integrators, PC2000 is reliable spare multi-parameter water quality controller for legacy water treatment systems. It restores automatic water chemistry monitoring and dosing control functions, extends service life of water treatment assets and avoids high-cost whole system renovation.
