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.

Market Intelligence & In-Depth Whitepaper

Chilean Industrial Landscape: Critical Demand for Resilient pH & ORP Sensors

Analyzing operating realities from the Atacama lithium salt flats to Antofagasta copper smelting and southern bio-industries.

Copper Hydrometallurgy & SX-EW Acid Control

Chile remains the world's leading copper producer. The Solvent Extraction and Electrowinning (SX-EW) circuits operate with concentrated sulfuric acid raffinate at elevated electrolyte temperatures (45°C to 65°C). Standard glass electrodes experience rapid gel dehydration and reference electrolyte depletion. Our high-temperature sensors incorporate pressurized gelled polymer electrolytes with double-junction diffusion barriers to maintain stability despite aggressive sulfate and chloride complexes.

Lithium Brine Purification in Salar de Atacama

Extracting lithium carbonate requires precise multi-stage fractional precipitation at alternating pH thresholds and thermal conditions. Saturated saline solutions routinely foul traditional single-ceramic junctions via crystallization. Our specialized sensors employ open annular liquid junctions and fluoroplastic porous diaphragms to completely mitigate salt bridging and galvanic drift in high-salinity brines.

Bio-Fermentation & Pulp/Paper Processing

From the cellulose processing mills in Biobío and Maule to biotech pharmaceutical installations in Santiago, process sensors undergo frequent Steam-in-Place (SIP) and Clean-in-Place (CIP) cleaning regimes using hot caustic and acid washes up to 130°C. Standard glass breaks or loses slope integrity; our formulation features alkali-resistant titanium-doped glass bulbs rated for extended high-temperature lifespans.

Global Macro Trends & Procurement Strategy

Shift to Industrial IoT & Direct Modbus Integration

Enterprise buyers are transitioning from analog probe-to-transmitter setups toward direct digital sensor architectures.

Direct Modbus RS485 & Distributed Automation

Chilean engineering contractors (EPCs) are simplifying panel layouts by specifying smart sensors with embedded microprocessors that communicate directly over RS485 Modbus RTU into distributed DCS systems, eliminating signal losses over extended copper cabling.

Predictive Electrode Health & Glass Diagnostics

Modern process management requires online predictive maintenance. Our advanced digital electronics continuously measure glass membrane impedance and reference junction resistance, warning operators before catastrophic diaphragm clogging shuts down flotation or leaching operations.

Standardized Form Factors: PG13.5 & S8 Quick-Disconnect

Standardizing inventory reduces operational risk across multi-site mining and processing clusters. Our pH/ORP electrodes are engineered with universal PG13.5 threads and IP68-sealed S8/VP connectors, ensuring 100% mechanical interchangeability with existing European and North American flow assemblies.

Factory 4.0 Infrastructure

Precision Sensor Fabrication: Agile Supply Chain for South America

Combining end-to-end automated manufacturing with stringent calibration standards to provide dependable delivery schedules for overseas projects.

Dedicated High-Temperature Sensor Laboratory

Operating China's pioneering thermal electrochemical validation facility, we stress-test 100% of high-temperature sensor batches through continuous 130°C thermal cycles under 0.6 MPa pressure to guarantee zero structural cracking or reference seal failure during on-site commissioning.

48-Hour Burn-In & Multi-Point NIST Traceability

Every sensor undergoes a mandatory 48-hour electronic aging procedure followed by 3-point buffer calibration (pH 4.01, 7.00, 10.01) with traceable certificates. This eliminates startup drift and ensures out-of-the-box accuracy for Chilean process technicians.

Rapid OEM/ODM Customization & Direct Air Logistics

Whether your project requires custom insertion depths (120mm to 450mm), customized cable lengths up to 50 meters, or private labeling for South American instrumentation distributors, our scalable factory lines deliver within 7-14 business days via Santiago international shipping hubs.

Technical Guidance & Application Knowledge

Frequently Asked Questions: Chilean Industrial Deployments

Engineered answers regarding slurry abrasion, temperature compensation, and local supply chain logistics.

How do BOQU sensors withstand abrasive copper ore slurries in Chilean flotation circuits?

Slurry abrasion rapidly erodes standard thin-bulb glass. Our sensors for heavy mineral processing feature hemispherical thickened glass membranes (up to 4x standard wall thickness) combined with annular PTFE liquid junctions. This prevents physical scouring of the reference electrolyte and maintains steady potential readings even in high solid-percentage pulp lines.

What prevents reference electrolyte poisoning in sulfurous or high-sulfate media?

In sulfide-rich hydrometallurgical processing, sulfide ions (S²⁻) penetrate reference junctions and react with silver chloride (AgCl) to form silver sulfide precipitates, causing junction blockage and reading failure. Our high-temperature sensors employ a double-salt-bridge design with an intermediate electrolyte chamber free of silver ions, completely isolating the primary Ag/AgCl reference element from chemical attack.

Can these electrodes integrate with existing plant transmitters from Emerson, Endress+Hauser, or Mettler Toledo?

Yes. Our analog sensors utilize standardized VP6, VP8, and S8 coaxial connectors compatible with all standard industrial transmitters requiring mV input from high-impedance glass electrodes. Additionally, we integrate Pt100, Pt1000, or NTC30K thermistors directly inside the sensor body for seamless automated temperature compensation (ATC).

What is the typical shipping lead time and customs support for shipments to Chile?

Standard wholesale orders are packaged in vibration-damped export cartons and dispatched from Shanghai within 3-5 business days. Air shipments to Arturo Merino Benítez International Airport (SCL) in Santiago take approximately 4-7 transit days. We provide comprehensive documentation for Chilean customs clearance, including Commercial Invoices, Packing Lists, Certificates of Origin (Form F for China-Chile FTA preferential tariffs), and factory calibration certificates.
