Harsh Chemical pH Electrode Applications

The LT3900C High-Temp Complex Media pH Sensor is specifically engineered to survive where conventional pH electrodes fail. Its unique intermediate electrolyte system and double liquid junction make it the ultimate solution for the following demanding industries:

● Harsh Chemical & Chlor-Alkali Processing: Standard sensors degrade rapidly in complex chemical synthesis. The LT3900C resists chemical reactions with strong acids, alkalis, and solvents, ensuring precise pH monitoring in aggressive chlor-alkali production and complex chemical mixtures.
● High-Temperature Sugar Refining & High-Protein Media: High temperatures combined with viscous, organic-rich media (like sugar syrups or protein-heavy fluids) easily coat and blind standard sensors. This electrode maintains a stable reading and resists organic fouling even at elevated temperatures, drastically reducing maintenance frequency.
● Electronics Electroplating & Heavy Metal Wastewater: Heavy metal ions are notorious for poisoning the reference junction of standard pH sensors. The LT3900C’s robust anti-pollution design specifically targets and repels heavy metal contamination, making it ideal for circuit board manufacturing and electroplating effluent.
● High-Salt & Ammonia Wastewater Treatment: Environments with extreme osmotic pressure (high salt) or aggressive ammonium ions easily disrupt standard electrolytes. Tailored for these exact conditions, it delivers exceptionally long service life in printing and dyeing wastewater, ammonia-rich streams, and desalination brines.
