Is BOQU a manufacturer or a trading company?

BOQU is a manufacturer. Founded in 2007, Shanghai Boqu Instrument Co., Ltd. designs, produces and tests its sensors and analyzers in two Shanghai facilities (Kangqiao and Lingang) with 4,632 m² of floorspace, 200+ employees and an annual output of more than 100,000 instruments.

Which certifications do BOQU water quality instruments hold?

Production is managed under ISO 9001 and ISO 14001 systems, and products carry CE, SGS and FDA related certifications. The pH5806 high temperature pH sensor has also been awarded the Shanghai Brand certification.

What signal outputs and communication protocols are available?

Depending on the model, BOQU online analyzers provide 4-20 mA analog outputs, relay alarm contacts and RS485 Modbus RTU communication. IoT digital sensors output RS485 Modbus RTU directly, so they can connect to PLC, DCS, SCADA or cloud gateways without a separate transmitter.

Can BOQU sensors be used in high-temperature fermentation and steam sterilization?

Yes. BOQU operates a dedicated high-temperature water quality sensor laboratory, and its high-temperature pH and DO sensors such as the pH5806 and DOG-208FA are designed for bioreactors, fermenters and hot process lines that undergo repeated steam sterilization.

Do you offer OEM and ODM services?

Yes. BOQU supports OEM and ODM projects including private labeling, custom housings, cable lengths, measuring ranges, firmware and communication protocols, backed by an in-house R&D team.

What information should I provide to get the right analyzer recommendation?

Please share the parameters to measure, expected range, water type, process temperature and pressure, installation method (immersion, flow-through or pipeline), required output signal, power supply and any local compliance standard. BOQU engineers will then recommend a suitable configuration.

Local Industrial Ecosystem

High Temperature pH & ORP Sensor Deployment Across Greater Houston & Texas Gulf Coast

Strategic analysis of analytical instrumentation demands within the energy capital of the world, spanning harsh petrochemical cracking units to clean biomanufacturing corridors.

Houston Ship Channel & Baytown Refining

The Houston Ship Channel hosts one of the largest petrochemical complexes on earth. Catalytic hydrotreaters, sour water strippers, and amine regeneration columns run continuously between 80°C and 125°C with severe sulfide and phenol presence. Standard pH sensors suffer rapid reference junction poisoning and electrolyte depletion within 72 hours. BOQU's pressurized polymer gel reference systems withstand aggressive H₂S/NH₃ environments, providing Texas petrochemical operators with reproducible measurement life exceeding 12 months.

Texas Medical Center & Bioprocess Corridors

Houston's burgeoning life science initiatives in Sugar Land, Pearland, and Texas Medical Center demand clean-in-place (CIP) and steam-in-place (SIP) compliance. Repeated 121°C–130°C autoclaving cycles typically cause thermal glass stress and calibration drift in conventional sensors. Our high-purity alkali-resistant glass membranes and S8/PG13.5 threaded sanitary connections guarantee sterility integrity and sub-second drift recovery post-cycle.

ERCOT Thermal Power & Cogeneration SWAS

With the rapid growth of industrial cogeneration plants supplying Texas refineries, steam and water analysis systems (SWAS) require constant vigilance. High temperature high-pressure condensate and boiler feedwater lines require extreme pH stabilization (pH 9.0–9.6 with morpholine/ammonia) and oxidation-reduction potential monitoring to avoid flow-accelerated corrosion (FAC) and turbine blade silica deposition.

Technical Clarifications

Frequently Asked Questions: High Temperature pH & ORP Sensors in Houston Operations

Addressing common queries from Gulf Coast plant instrumentation managers, bioprocess engineers, and refinery automation technicians.

How does a high-temperature pH sensor withstand continuous 130°C thermal exposure without drifting?

Standard pH electrodes rely on liquid KCl electrolytes and standard glass formulations that suffer rapid alkaline error and electrolyte boil-off above 80°C. BOQU's high-temperature series incorporates specialized lithium-doped heavy-duty glass impedance membranes, polymerized high-viscosity gel references, and an internal pressurization barrier. This architecture prevents boiling, suppresses junction potential drift, and permits direct steam sterilization (SIP) at 130°C with instant slope recovery.

Can these sensors handle harsh sulfur compounds and hydrocarbons common in the Houston Ship Channel?

Yes. Petrochemical processes such as amine treaters, sour water separators, and crude desalters contain hydrogen sulfide (H₂S), which reacts with standard silver/silver chloride reference wires to precipitate insoluble silver sulfide (Ag₂S), completely blocking ceramic junctions. BOQU high-temperature sensors employ a double-junction reference design with ion-trap diffusion barriers and porous Teflon junctions that resist oily hydrocarbon coatings and sulfide poisoning.

What connector types and thread fittings are available for Texas plant retrofits?

Our sensors come standard with industrial PG13.5, 3/4-inch NPT, or 1-inch NPT insertion fittings, making them directly compatible with retractable assemblies, flow-through sample chambers, and sanitary bioreactor ports. Signal connections include S8, VP (VarioPin), and direct low-noise waterproof coaxial leads, as well as RS485 Modbus RTU digital connectors for direct DCS integration.

What is the difference between pH and ORP monitoring in high-temperature wastewater and cooling towers?

pH measures the active hydrogen ion concentration (acidity or alkalinity), essential for controlling neutralizer chemical dosing and mitigating acid corrosion. ORP (Oxidation-Reduction Potential) measures the electron activity of the solution using a solid platinum or gold ring. In hot petrochemical effluent and cooling circuits, ORP confirms the biological disinfection effectiveness of oxidizers (e.g., sodium hypochlorite or bromine) and ensures the complete reduction of hexavalent chromium or toxic residual oxidizers.

Does BOQU support OEM customization and fast shipment to Houston, TX?

Yes. Founded in 2007 with dual facilities spanning 4,632 m² and an annual capacity exceeding 100,000 instruments, BOQU supplies private-label and customized sensor solutions to major process automation brands, Texas distributor networks, and end-users worldwide. We offer fast air delivery options directly to Houston George Bush Intercontinental Airport (IAH) or local sea freight through the Port of Houston.
