BOQU Sensor Ph Sensor Ph Quality Assurance

Product Overview

- Model CPH-809X industrial online desulfurization pH electrode from BOQU, designed for continuous pH monitoring in limestone–gypsum wet flue gas desulfurization (FGD) systems.

- Measurement range pH 0.0–14.0, temperature range 0–95 °C, accuracy ±0.1 pH; temperature compensation via PT100 available; PPS construction, 3/4" NPT connections and low‑noise cable.

- Built to operate in high‑solids, corrosive slurry environments and to help maintain the recommended circulating slurry pH range (about 4.8–6.0) for optimal SO2 absorption and process stability.

Product Features

- Large outer polymer electrochemical interface provides a much bigger liquid contact area for faster response than conventional liquid–liquid junction electrodes.

- Non‑porous design eliminates direct exchange between process liquid and the internal reference, reducing contamination and corrosion of the reference/electrolyte.

- Less prone to clogging than pore‑type junctions; can be fitted with temperature compensation and electrode grounding to improve measurement stability in the field.

- Durable PPS construction and threaded process connections for easy installation; low‑noise cable for reliable signal transmission.

- Designed for high pressure/robust operation (specs list 6 bar, with engineered structure support for much higher endurance).

Product Value

- Enables accurate, continuous pH control of circulating slurry, maximizing SO2 absorption while avoiding excessive scaling, clogging or corrosion.

- Improves desulfurization efficiency and limestone utilization by keeping the slurry in the optimal pH window (4.8–6.0).

- Lowers maintenance and replacement costs through long service life and reduced fouling/contamination risk.

- Supports regulatory and environmental goals by helping maintain effective pollutant removal and stable process operation.

Product Advantages

- Longer working life (reported at least three times that of conventional electrodes) due to non‑porous, contamination‑resistant design.

- Faster response and greater measurement stability from the large polymer interface and optional temperature compensation/grounding.

- Robust construction for harsh industrial slurry environments—resistant to fouling, clogging and corrosion.

- Manufactured and quality‑inspected by BOQU with experienced R&D support and full part inspection before assembly, offering reliable performance and after‑sales support.

Application Scenarios

- Online pH monitoring and control in limestone–gypsum wet flue gas desulfurization systems at power plants and large industrial boilers.

- Process control in industrial desulfurization plants and chemical facilities where SO2 absorption and slurry pH are critical.

- Harsh slurry or high‑solids wastewater streams where conventional pH electrodes foul or corrode easily.

- Any industrial application requiring durable, continuous pH measurement under corrosive, high‑temperature or high‑pressure slurry conditions.
