Yokogawa Electric Corporation PH72SN-32-AA S2.01 pH Sensor

The Yokogawa PH72SN-32-AA S2.01 pH Sensor is a field-replaceable glass-electrode designed for use with the PH72 personal pH/ORP meter series, delivering accurate pH measurements in portable testing applications. Its compact, rugged design suits both lab benches and on-site work, and it includes integrated temperature sensing for temperature-compensated readings when paired with the PH72 handheld meter. The sensor uses a 6-pin connector interface with an integrated cable (length varies by suffix), enabling quick field swaps. Target applications include water quality testing, wastewater treatment, chemical processing, and environmental monitoring, where real-time pH data supports maintenance checks, sampling, and field diagnostics. Specifications confirm a general-purpose glass electrode, a typical measurement range of 0–14 pH (sensor dependent), and compatibility with PH72 for IP67-rated waterproof operation.
