Orp Controller Industrial PH/ORP Meter Wholesale - BOQU

Product Overview

- Model: PHG-2081S Digital pH/ORP Meter from BOQU (Shanghai Boqu Instrument Co., Ltd.).

- Online analyzer for pH, ORP (mV) and temperature using a digital pH/ORP sensor with RS485 Modbus.

- Panel, wall or pipe mounting; IP65-rated ABS housing; overall size 144×144×104 mm (cutout 138×138 mm).

- Power: 90–260 V AC, 50/60 Hz.

Product Features

- Digital sensor interface: sensor carries calibration data and communicates via RS485 Modbus RTU.

- Measurement ranges: pH -2.00 to 16.00 (±0.01 pH resolution), ORP -2000 to +2000 mV (1 mV resolution), temperature -30.0 to 130.0 °C (0.1 °C resolution).

- Accuracy: ±0.01 pH, ±1% FS for ORP, ±0.5 °C for temperature. Input impedance > 10^12 Ω.

- Outputs and control: two isolated 4–20 mA outputs (selectable for pH/ORP/temperature), RS485 communication, and three relays (two for high/low alarm, one for cleaning/time control).

- Data capabilities: onboard data recording and history curve view; calibration saved in sensor to speed sensor swaps.

- Designed for long-distance installation and harsh environments; supports predictive maintenance features.

Product Value

- Reduces downtime and maintenance costs by storing calibration in the sensor and enabling quick sensor replacement.

- Enables remote monitoring and integration into SCADA/automation via RS485 Modbus and isolated analog outputs.

- Improves process control and compliance through continuous, high-accuracy online measurement and historical data logging.

- Supports predictive maintenance to anticipate issues before they impact operations, lowering total cost of ownership.

Product Advantages

- Digital-sensor architecture: calibration portability, improved signal integrity and reduced wiring issues over long runs.

- Robust industrial design: IP65 protection, ABS housing, and relay control for automatic cleaning or alarm actions.

- Flexible outputs and communications: isolated 4–20 mA channels plus RS485 for multi-system integration.

- High precision and wide measurement ranges suitable for demanding applications.

- Built-in datalogger and history visualization simplify troubleshooting and quality traceability.

Application Scenarios

- Wastewater treatment and effluent monitoring (pH/ORP control and compliance).

- Drinking water treatment and distribution system monitoring.

- Industrial process control in chemical, pharmaceutical and food production lines.

- Fermentation, brewing and other biotech processes requiring tight pH control.

- Environmental monitoring, aquaculture, cooling towers and any application needing continuous pH/ORP/temperature measurement and automated control.
