Features

✅ Flow‑Through / Bypass Flow‑Cell Installation Optimized Specially designed for flow‑through cell mounting (bypass pipeline sampling). Sensors install inside flow‑through chamber, eliminate air‑bubble disturbance, keep stable sample flow, get repeatable & reliable readings. Also supports wall‑mount / embedded installation for controller unit; sensor also compatible with immersion bracket as optional solution.

✅ Multi‑Parameter Simultaneous Measurement One controller supports multiple sensors: Residual Chlorine, pH/ORP, Turbidity, Conductivity, Dissolved Oxygen, Ammonia‑Nitrogen, COD, Temperature. All parameters display on the same LCD screen. Support Chinese / English menu switch for global operation.

✅ High‑Precision Measuring Performance

Residual Chlorine: 0‑20mg/L, resolution 0.001mg/L, accuracy ±1%FS

pH: 0‑14pH, resolution 0.01pH, accuracy ±0.1pH

Turbidity: 0‑20 / 400 /4000 NTU optional, accuracy ±3%FS

Conductivity: 0-2000us/cm

Automatic / manual temperature compensation function built‑in.

✅ Rich Signal Output & Industrial Communication

Analog: Dual‑channel 4‑20mA current output, freely assign measuring parameters

Digital: RS‑485 Modbus‑RTU, optional RS232, Bluetooth, GPRS for IoT data upload

3 groups of relay alarm outputs, freely set high/low alarm threshold and adjustable hysteresis for automatic dosing & interlock control.

✅ Powerful Data Logging & Calibration Function Support SD card data storage, historical log query & data export. Support multi‑point pH calibration, single‑point residual chlorine calibration, factory reset function. Menu password protection (default password:1111).

✅ Rugged Controller Hardware ABS controller housing; dimension:180×157×84.5 mm; embedded cut‑out size:138×138 mm. Power supply: 220VAC / 24VDC. Operating ambient:‑20~50℃, humidity ≤90%. Low power consumption ≤3W.

✅ Easy Maintenance & Flexible Configuration Modular sensor connection; sensors can be individually replaced. Support self‑cleaning switch trigger. Measuring range, alarm value, baud rate, address can be configured locally on screen or via Modbus communication.
