Municipal Water & Desalination
Continuous residual chlorine, turbidity, and TOC tracking ensure safe drinking water distribution networks. Multi-parameter skid systems provide automated feedforward and feedback dosing control for coagulants and sanitizing chemicals.
Thermal & Nuclear SWAS Loops
Steam and Water Analysis Systems (SWAS) require trace-level precision. Our silicate, phosphate, sodium, hydrazine, and differential conductivity monitors protect supercritical boilers, heat exchangers, and turbines against scaling and corrosion.
Pharmaceutical & Bioprocess
Narrow biological reaction envelopes require specialized high-temperature sensors capable of zero baseline drift. We deliver sanitary-grade pH and dissolved oxygen probes certified for SIP/CIP regimes in high-value bioreactors.
Recirculating Aquaculture (RAS)
Protecting high-density marine habitats with multi-channel dissolved oxygen, pH, salinity, and un-ionized ammonia networks. Instant automated relay alarms activate aeration and degassing loops before biological stress occurs.
Hydroponics & Advanced Agriculture

| Target Parameter | Measurement Methodology | Common Industrial Application | Engineering Specification Guideline |
|---|---|---|---|
| pH & ORP | Glass Electrode / Platinum Redox | Wastewater Neutralization, Bioreactors, Cooling Loops | Specify high-temperature solid gel electrolytes for processes exceeding 80°C or with rapid SIP/CIP cycles. |
| Dissolved Oxygen (DO) | Fluorescence Optical / Polarographic | Aeration Basins, RAS Aquaculture, Biopharma Fermentation | Optical sensors eliminate electrolyte replacement in dirty wastewater; polarographic units excel in autoclavable ports. |
| Conductivity & TDS | 2/4-Electrode / Toroidal Inductive | Boiler Feedwater, CIP Concentration, RO Pretreatment | Select inductive (toroidal) sensors for high-conductivity chemicals, slurries, or aggressive acids to avoid electrode scaling. |
| Turbidity & TSS / MLSS | Infrared 860nm Scattered Light | Clarifiers, Filter Effluent, Sludge Concentration | Mandate automated mechanical wipers in high-solids waste streams to eliminate optical window fouling. |
| Residual Chlorine | Constant-Voltage Amperometric | Drinking Water Disinfection, Cooling Tower Biocide Control | Pair with continuous pH and temperature compensation loops to balance fluctuating hypochlorous acid dissociation. |
| Nutrients (COD / TP / TN) | Wet Chemical Digestion / UV-Vis Spectrometry | Municipal & Industrial Outfall Compliance | Verify alignment with EPA, ISO, or local environmental protection standards prior to reagent selection. |

Buyer Guidance
Frequently Asked Procurement Questions
Clear, direct answers regarding our manufacturing standards, customization, and technical parameters.
Is BOQU an original manufacturer or an export trading intermediary?
BOQU is an original equipment manufacturer founded in Shanghai in 2007. We manage our own R&D labs, sensor glass-blowing workshops, automated SMT lines, and assembly facilities spanning 4,632 m² across our Kangqiao and Lingang factories, yielding over 100,000 instruments annually.
What communication outputs are supported for modern SCADA/DCS systems?
Our online transmitters feature isolated 4-20mA analog loops with bidirectional RS485 Modbus RTU connectivity. Furthermore, our standalone IoT smart digital sensors transmit RS485 Modbus RTU directly from the sensor body, enabling clean integration into PLC or IoT gateways without a separate controller.
How do BOQU high-temperature sensors survive repeated SIP/CIP sterilization?
Developed within China's first dedicated high-temperature sensor laboratory, models like our pH5806 utilize specialized thermotolerant glass formulas and pressurized polymer gel references. This engineering prevents electrolyte boiling, poisoning, and baseline shift under continuous 130°C steam conditions.
What OEM and ODM private label services can you provide for distributors?
We support turnkey private labeling including custom controller bezels, personalized firmware startup screens, tailored measuring scales, bespoke cable lengths, custom connector sockets (S8, VP, BNC), and specialized mounting hardware to fit your brand requirements.
What information is required to get a prompt, accurate quotation?
Please provide: your target measuring parameters (e.g., pH, COD, DO, Conductivity), the expected concentration range, operating temperature and line pressure, installation method (submersible immersion, flow-through chamber, or inline insertion), and preferred signal outputs.
What quality assurance steps are taken prior to factory dispatch?
Every single instrument undergoes a mandatory 48-hour continuous burn-in and thermal aging cycle. Sensor electrodes are multi-point calibrated using NIST-traceable standard buffer solutions, and full ISO 9001 inspection certificates are generated prior to dispatch.
