Ryton Body Flat Surface Electrode – FLS pH 800

The FLS 870 pH electrode line is designed for superior performance in demanding industrial applications. Built with a rugged Ryton body and an auto-cleaning flat pH surface, it ensures accurate and reliable measurement even in dirty liquids and aggressive solutions. A built-in Pt1000 temperature sensor enhances precision, while the wide junction design improves stability in the presence of suspended solids. The 870 electrodes feature a ¾” threaded connection, allowing easy in-line installation from the electrode bottom or submersible mounting from the electrode head. Specialized versions are available for unique requirements, including horizontal mounting (-HM), low-conductivity samples (-LC), and aggressive environments with HF <2% or low pH (-HF). A versatile and durable solution for continuous monitoring.
