Hydrofluoric Acid Resistant LT3700HF Online pH Sensor

Driven by its highly specialized HF-resistant glass membrane, the LT3700HF online pH sensor is uniquely engineered to survive where standard electrodes rapidly dissolve. By continuously withstanding up to 5000ppm Hydrofluoric Acid (HF), it delivers unparalleled measurement stability and reduces replacement costs across these highly corrosive industrial sectors:

Specialized Application Fields:
● Semiconductor Wafer Fabrication: Standard glass sensors are quickly destroyed by the hydrofluoric acid used in wafer etching and cleaning. The LT3700HF ensures continuous, high-precision pH monitoring in these aggressive chemical baths, preventing costly production downtime.
● Metal Treatment & Stainless Steel Pickling: Industrial pickling processes frequently utilize HF mixtures to strip surface impurities. This robust electrode effectively resists severe chemical corrosion, drastically reducing sensor replacement frequency for metallurgical facilities.
● Petrochemical & Refinery Operations: Designed for complex and hazardous media, the sensor maintains reliable, long-term measurement stability in petrochemical wastewater and alkylation processes that contain elevated fluoride levels.
● Heavy Steel Plant Wastewater: Effluents from steel manufacturing are notoriously acidic and abrasive. The LT3700HF’s double liquid junction and IP68 waterproof construction guarantee stable, anti-pollution monitoring for strict environmental compliance.
● Electronic Electroplating Facilities: The sensor provides fast (<10s) and accurate 0-14pH readings in the specialized, highly corrosive plating baths required for electronic component manufacturing, ensuring consistent surface finishing quality.
