應用
飲料罐裝(如牛奶、啤酒)。鍋爐给水中的測量(檢測限值1 ppb )
Reliable measurement of oxygen traces also under sterile and hygienic conditions; signal-stable and robust.
High resolution of low oxygen concentrations, simple and cost-efficient sensor calibration in ambient air. No calibration gases. High signal stability also in the presence of high CO2 partial pressures. FDA-conforming material with extremely smooth polished surface. Simple maintenance due to modular design. Sterilizable, autoclavable, and CIP-capable. Also suitable for hazardous areas.
Applications
Beverage filling (e.g. milk, beer). Measurement in boiler feed water (detection limit 1 ppb)
