Yokogawa Electric Corporation FU20-VS-T1-FTD pH Composite Electrode Sensor

The Yokogawa FU20-VS-T1-FTD pH Composite Electrode Sensor is a 4-in-1 integrated sensor that measures pH, ORP (redox), and temperature in a single inline unit for industrial liquid analysis. With a glass pH electrode and a platinum ORP electrode, plus an Ag/AgCl double-junction reference with ion trap and a Pt1000 RTD temperature element, it provides accurate, multi-parameter readings in harsh process environments. The PVDF body offers high chemical resistance, and the 3/4" NPT threaded (double-ended) process connection supports in-line, immersion, or flow fitting mounting for pipelines, tanks, and flow fittings in chemical processing, wastewater treatment, food and beverage processing, and power generation facilities. Its Variopin (VS) connector with an ID chip enables secure, plug-in integration, while features such as long-life electrolyte, PTFE diaphragm, and high fouling resistance help maintain stable measurements. Common replacements include Yokogawa FU20-VP-T1-FTD, Yokogawa FU20-05-T1-NPT, and Yokogawa PH20 Series Sensor.
