Wholesale Sulfuric Acid Analyzer Manufacturers & Suppliers

For concentrated sulfuric acid (93–98%), toroidal (electrodeless) inductive conductivity is the global industry standard. In this range, conductivity correlates tightly with acid concentration. Because the toroidal coils are fully encased in virgin fluoropolymer (PFA/PTFE), no conductive metal components contact the acid. This eliminates electrode corrosion, polarization errors, and frequent re-calibration requirements.

The relationship between sulfuric acid concentration and electrical conductivity is non-linear and reverses direction past certain thresholds (such as around 30% and 85%). BOQU's online analyzer controllers utilize dedicated application firmware with piecewise mathematical models. Operators select the target operating window (e.g., 0–20%, 20–40%, or 90–99%). The analyzer then correlates calibrated inductive values with high-speed PT1000 temperature data to calculate precise concentration without ambiguous readings.

Yes. Shanghai BOQU operates a dedicated high-temperature chemical sensor laboratory. Our high-temperature sensor configurations use compression-molded Virgin PFA bodies and specialized internal potting compounds rated for continuous operating temperatures up to 130°C (and transient steam sterilization cycles). For process lines exceeding these temperatures, we provide engineered bypass cooling sample conditioning panels that regulate sample temperatures prior to measurement.

BOQU online analyzers come standard with dual isolated 4–20 mA analog outputs (assignable to concentration and temperature), dual programmable SPDT relay contacts for high/low alarms or proportional pump dosing, and standard RS485 Modbus RTU digital communication. Direct IoT digital sensors can also connect directly to a plant PLC or edge gateway without requiring an intermediary transmitter wall-mount box.

Because electrodeless inductive sensors experience no electrode wear or galvanic degradation, routine drift is minimal. In steady-state clean chemical pipelines, inspection intervals typically range from 6 to 12 months. Calibrations are easily performed using standard resistance-loop calibration resistors or by referencing a verified laboratory titration sample via the transmitter's intuitive single-point process offset menu.

Yes. As a genuine Shanghai manufacturer, OEM and ODM projects form a core pillar of our international business. We offer custom enclosure silk-screening, custom software boot logos, tailored sensor cable lengths, personalized measurement range calibrations, and private-label documentation for authorized distributors and plant engineering firms worldwide.
