A comprehensive examination of why the UAE's industrial infrastructure demands advanced high-temperature electrochemistry beyond standard commercial instrumentation.
Thermal seawater desalination facilities across Jebel Ali, Fujairah, and Taweelah operate multi-stage flash (MSF) and multi-effect distillation (MED) evaporators where brine temperatures continuously cycle between 65°C and 115°C. Traditional pH bulbs suffer rapid alkaline error and electrolyte dilution under super-saline, hypersaturated conditions, causing premature loss of calibration and control failure in antiscalant acid dosing.
From the massive refining complexes in Ruwais to gas treatment facilities in Habshan and Shah, Abu Dhabi’s downstream industry handles severe sulfur and sour gas (H₂S) fractions. High-temperature ORP and pH tracking is essential in amine scrubbing, sour water strippers, and sulfur recovery units (SRU) where process liquors reach 90°C–125°C under high backpressures, rapidly poisoning conventional silver/silver chloride reference junctions.
Urban cooling networks (Empower, Tabreed) and industrial effluent plants in KIZAD and Dubai Industrial City operate massive cooling towers subjected to ambient ambient thermal loads surpassing 50°C and blowdown water exceeding 60°C. Accurate pH and ORP tracking prevents micro-fouling, legionella outbreaks, and scale buildup without false readings caused by thermal drift.
In standard laboratory conditions, a pH glass membrane lasts years. However, in the UAE's industrial ecosystem, high operating temperatures (80°C–130°C) coupled with hypersalinity (TDS exceeding 45,000 mg/L in desalination reject) accelerate the dissolution of the hydrated gel layer on glass bulbs by up to 300%. Standard liquid KCl references suffer rapid back-diffusion of sulfides and heavy ions, leading to precipitation of Ag₂S at the porous ceramic junction and total signal loss within days. Shanghai BOQU’s high-temperature product line specifically solves this dilemma via high-alkali-resistant glass formulations and pressurized polymerized solid electrolyte matrices.

Combining proprietary glass chemistry, automated micro-assembly, and rapid OEM customization to out-spec legacy European instrumentation while reducing total cost of ownership by 40–60%.
BOQU utilizes proprietary lithium-barium glass formulations specifically blown to minimize alkaline metal errors (sodium ion error at pH >11 and temperatures >80°C). Our bulbs maintain low membrane impedance (<250 MΩ at 25°C) ensuring rapid response time (<10 seconds) even in oily or high-viscosity liquors.
Eliminate reference poisoning with our non-aqueous cross-linked polymerized gel references. Pre-pressurized to 4–6 bar internally, our sensors ensure continuous micro-efflux of reference ions through annular ceramic or PTFE diaphragms, preventing sour gas (H₂S, cyanides) or hydrocarbon infiltration into the inner Ag/AgCl half-cell.
BOQU established one of China’s first dedicated industrial high-temperature water quality sensor calibration and stress-testing facilities. Every high-temp electrode batch undergoes 48-hour thermal aging at 130°C and cyclic pressure pulsation before export, backed by full ISO 9001, ISO 14001, and CE factory certificates.
Unlike Western suppliers with 12 to 24-week lead times, BOQU maintains extensive inventory of specialized borosilicate glass tubes, platinum pins, and pre-molded PEEK/Ryton housings. We fulfill bulk orders and customized OEM specifications (immersion lengths from 120mm to 420mm, VP/S8/Variopin connectors, direct RS485 Modbus) within 7–14 days.
Our high-temperature sensors interface seamlessly with Emerson, Yokogawa, Endress+Hauser, and ABB controllers via standard analog inputs or digital RS485 Modbus RTU transmitters (pHG-2081Pro), eliminating the need for expensive proprietary transmitter replacements in UAE plant retrofits.
Supported by our experienced export engineers, we offer door-to-door DDP air and sea shipping straight to Jebel Ali Free Zone (JAFZA), Abu Dhabi Ports (KIZAD), and Sharjah industrial areas, accompanied by complete certificate of origin (COO), SASO/UAE compliant documentation, and remote commissioning assistance.

Our high-temperature sensors employ a uniquely synthesized lithium glass membrane characterized by high mechanical strength and low thermal expansion coefficients. The internal reference system features a pressurized polymeric gel saturated with potassium chloride (KCl), coupled with a diffusion-retarding double-chamber salt bridge. This prevents electrolyte expansion, boiling bubbles, and reference loss during 121°C–130°C steam sterilizations, ensuring the sensor maintains precise slope and zero-point calibration upon cooling.
Yes. BOQU designs its industrial glass and titanium sensors to conform with international standard form factors. Our electrodes feature standard PG13.5 mechanical threads, standard insertion lengths (120mm, 225mm, 325mm, 425mm), and universal connectors including S8, VP6, Variopin, and standard coax BNC. They drop directly into your existing static, flow-through, or retractable housing assemblies without modification.
In thermal MSF/MED evaporator recirculating brine at 80°C–105°C and 60,000 ppm TDS, standard laboratory electrodes typically fail within 10 to 20 days. BOQU’s high-temperature, high-salinity formulation delivers a continuous operating lifespan of 6 to 12 months with periodic monthly 2-point buffer calibrations, significantly lowering replacement frequency and manual maintenance man-hours.
