pH Sensors & Transmitters

pH Sensors & Transmitters

Endress+Hauser’s pH Sensors & Transmitters measure acidity/alkalinity across industries. The range includes glass, glass‑free ISFET and enamel electrodes for stable, fast‑changing or sticky media, for hygienic or hazardous duty, paired with Liquiline transmitters forming complete measuring points.

pH is among the most quality‑critical process variables. Memosens 2.0 stores more calibration/process data, resists moisture, and enables predictive maintenance and plug‑and‑play handling. Liquiline adds multichannel expansion, Heartbeat diagnostics, and web‑enabled fieldbus/Ethernet connectivity.

Typical applications span water & wastewater, chemicals, food & beverage, life sciences and power - where pH steers neutralization, dosing, fermentation, and quality. Use ISFET where glass breakage or solvents matter; enamel for long‑term stability/low maintenance; and robust glass for general duty.

Systems include fixed, immersion, flow, and retractable assemblies, plus automated cleaning/calibration for harsh or hygienic duties. Liquiline CM42 (two‑wire) and CM44x (multichannel) accept Memosens probes and provide 4–20 mA, HART, PROFIBUS, PROFINET, Modbus, EtherNet/IP and web‑server integration.
