Hot Sale Ph Probe Sensor Company

Product Overview

BOQU BH-485-PH is a digital online pH probe sensor designed for continuous industrial monitoring. It combines an imported composite electrode with built?in temperature sensing and on?board automatic temperature compensation, and communicates over RS485 using the Modbus RTU protocol. The unit is available for submersion, inline or circulation installations and is housed in ABS.

Product Features

- Measurement: pH 0.0–14.0 and temperature 0–50.0 °C.

- Accuracy & resolution: pH ±0.1 with 0.01 pH resolution; temperature ±0.5 °C with 0.1 °C resolution.

- Built?in automatic temperature compensation and automatic standard?solution identification.

- Communication: RS485 (Modbus RTU) for remote readings, settings and remote calibration; supports long?distance transmission (specified up to ~500 m).

- Power & build: 12V or 24V DC (typical 24V), ~1W consumption, 5 m cable standard (customizable), ABS housing, rapid response and low maintenance.

Product Value

The sensor delivers reliable, real?time pH and temperature data to improve process control and compliance. Its remote calibration and configuration reduce onsite maintenance and labor costs, while stable long?term operation minimizes downtime and replacement frequency. Standard Modbus output simplifies integration into SCADA/PLC systems for centralized monitoring and automated control.

Product Advantages

- High stability and long electrode lifetime due to imported composite electrode design.

- Real?time automatic temperature compensation and automatic reference calibration identification for consistently accurate readings.

- Strong anti?interference performance and industry?standard Modbus RTU over RS485 for robust, long?range data transmission.

- Remote parameter setting and calibration enable convenient maintenance and reduce service visits.

- Manufactured under international quality practices with scalable cable/installation options for different installations.

Application Scenarios

- Industrial wastewater and sewage monitoring and control.

- Municipal and commercial water treatment plants (online process control).

- Chemical processing, pulp & paper, and other industrial process streams requiring continuous pH monitoring.

- Inline/recirculation systems and submersible monitoring points in aquaculture, food & beverage, laboratories and environmental monitoring installations.
