Engineered for high-temperature stability, extreme acid-alkali durability, and real-time Modbus integration across critical chemical and water utilities.
Modern process optimization requires transitioning from legacy analog galvanic cells to intelligent solid-electrolyte and digital analytical nodes.
Global pharmaceutical bioreactors and enzymatic food processing plants require pH electrodes capable of enduring repeated Steam-in-Place (SIP) and Clean-in-Place (CIP) regimes up to 130°C without zero-potential drifting or reference junction poisoning. Our proprietary gelled polymerized electrolytes offer sustained ion flux under continuous high thermal pressure.
Bypassing costly secondary transmitters, direct-to-bus RS485 Modbus RTU sensors allow DCS, SCADA, and distributed IoT gateways to extract unadulterated millivolt readings, internal impedance metrics, and operating temperature records directly, eliminating line noise interference over long-distance cable topologies in massive chemical plants.
Wastewater treatment plants dealing with severe suspended solids (MLSS) and harsh heavy-metal effluent experience rapid diaphragm failure with standard ceramic frit electrodes. Deploying PTFE annular porous diaphragms and solid polymer electrolytes creates impenetrable barriers against sulfide fouling and organic coatings.

Deploying specialized analytical instrumentation adapted to strict regional environmental laws and process chemistry controls.
Microorganisms synthesize secondary metabolites exclusively within tight electrochemical bands. Our high-temperature sensors integrate S8 / VP / PG13.5 process fittings compatible with standard port adapters. They remain impervious to autoclaving drifts, ensuring compliance with FDA 21 CFR Part 11 electronic data capture when integrated with digital transmitter systems.
In thermal and nuclear power utilities, sub-ppb changes in water purity precipitate massive boiler tube scaling and turbine blade erosion. BOQU Steam and Water Analysis Systems (SWAS) merge high-precision pH, cation conductivity, and dissolved oxygen instruments with sample conditioning coils to safely depressurize and de-temperature boiling superheated steam.
Textile, galvanic plating, and chemical manufacturing parks face rigorous discharge norms (such as EPA NPDES and EU Industrial Emissions Directive). Online multi-parameter analyzers automate chemical dosing for coagulation, neutralization, and heavy-metal precipitation tanks, preventing compliance penalties before treated water discharges into municipal streams.

Eliminating early life field defects via exhaustive 48-hour burn-in procedures, baseline calibrating against standard NIST-traceable buffer standards with documented factory calibration certificates.
Ensuring frictionless cross-border distribution and engineering compliance for OEM partners and industrial procurement managers.
Fully certified quality and environmental control frameworks governing raw material sourcing, automated glass blowing, electrolytic filling, electronic PCB assembly, and end-of-line packaging.
Full CE conformity for electromagnetic safety and European compliance. Third-party audited manufacturing lines by SGS. FDA-registered materials suitable for non-invasive biopharma contact.
The prestigious "Shanghai Brand" mark was awarded to the pH5806 series in recognition of its benchmark performance, durability, and leadership in high-temperature electrochemical technology.
Shanghai BOQU Instrument maintains active instrument installations across 2,000+ enterprise customers in five continents. Notable field applications include:
Addressing core mechanical, electrochemical, and commercial inquiries for process engineers and distribution buyers.
Shanghai BOQU Instrument Co., Ltd. is an original manufacturer established in 2007. We operate two advanced manufacturing facilities in Kangqiao and Lingang, Shanghai, spanning 4,632 m² of specialized production space, fully equipped with automated glass manufacturing, PCB assembly, and sensor calibration workshops.
BOQU industrial sensors utilize pressurized double-junction chambers filled with specialized polymer gels, complemented by annular porous PTFE or ceramic diaphragms. This design creates positive internal osmotic pressure that blocks sulfides, cyanides, and heavy ions from migrating toward the Ag/AgCl reference element.
Yes. Our IoT digital pH sensors feature integrated micro-transmitters within the sensor housing. They output standardized RS485 Modbus RTU signals directly, allowing direct communication to PLCs, RTUs, DCS, or SCADA systems over distances up to 500 meters without intermediate analytical transmitters.
We provide end-to-end OEM and ODM services for global instrumentation brands. This encompasses private laser branding, custom body materials (Titanium, Hastelloy, PPS, PVDF), specific cable lengths and connectors (VP6, S8, BNC), custom calibration firmware, and customized communication register maps.
Our high-temperature series (such as the pH5806) employs specialized high-alkali glass formulations with low thermal expansion stress, along with solid polymer electrolytes that do not boil or cavitate at 130°C. Internal Pt100/Pt1000 RTD elements provide continuous dynamic Nernstian temperature compensation.
Standard catalog models are stocked for prompt delivery within 3–7 business days, while volume OEM orders ship in 2–3 weeks. Every instrument undergoes a mandatory 48-hour continuous burn-in procedure and multi-point buffer calibration in our accredited analytical testing laboratory before packaging.
