Selected high-temperature inline sensor models equipped with pressurized polymer electrolytes and high-alkali resistant glass membranes for Japan's high-purity production lines.
Analyzing thermal stability, chemical aggression, and micro-sensing challenges across the Keihin Industrial Area and Chiba-Tokyo chemical corridor.
Facilities across Nihonbashi Life Science Hub, Kawasaki King SkyFront, and suburban Tokyo focus heavily on cell culture, monoclonal antibody synthesis, and synthetic biology. Process batches require repeated Clean-In-Place (CIP) and Steam-In-Place (SIP) cycles at 121°C–135°C without recalibration shifts or diaphragm poisoning.
Kanto’s electronics supply chain relies on ultra-pure chemical etching, wafer wet processing, and high-temp neutralization loops. Sensors must exhibit zero heavy-metal leaching, ultra-fast response times to transient acid-alkali dumps, and robust resistance to hydrofluoric acid or concentrated hot surfactants.
Tokyo Metropolitan Bureau of Sewerage maintains strict discharge ordinances under the Water Pollution Prevention Act. Thermal cooling waters, chemical neutralization reactors, and scrubbers demand inline electrochemical electrodes that withstand corrosive gas-saturated condensates at sustained high temperatures.
Understanding the physics behind reference junction depletion, glass impedance spikes, and silver chloride precipitation at elevated temperatures.
Standard glass membranes exhibit exponential resistance increases as temperatures fluctuate, leading to measurement lag and high noise. BOQU uses proprietary alkali-resistant, low-impedance lithium glass formulations for ultra-fast Nernstian slope response.
Liquid electrolytes boil or rapidly dilute under 100°C+ conditions. Our sensors utilize high-viscosity, cross-linked polymer electrolytes pre-pressurized up to 6 bar, preventing process back-flow and eliminating the need for external pressurization housings.
Conventional porous ceramic junctions quickly foul with suspended proteins and heavy metals. BOQU’s open annular polymer or PTFE liquid junctions avoid crystalline blockages and silver sulfide (Ag₂S) deposition.
Equipped with integrated Pt100, Pt1000, or NTC30K RTD sensors encased directly next to the glass sensing bulb, enabling microsecond-precision automatic temperature compensation (ATC) across 0–130°C ranges.
