pH sensor - SE 557 for special requirements, high-precision measurement, using refillable liquid electrolyte. Digital, eliminates typical junction problems, achieves high-precision measurement in ultrapure water or heavily contaminated media and at high temperatures. Integrated refillable liquid electrolyte container. Ceramic junction; self-cleaning due to pressurization (continuous electrolyte outflow). Silver ion trap prevents junction scaling and contamination.
