Yokogawa Electric Corporation SC72SN Personal Conductivity Meter

The Yokogawa SC72SN Personal Conductivity Meter with Sensor is a handheld, portable analyzer designed for on-site measurement of liquid conductivity, combining a compact form factor with IP67 waterproof protection and battery operation. This unit includes a dedicated SC72SN conductivity sensor and delivers measurements from 0 to 2000 mS/cm (sensor dependent) with automatic temperature compensation (NaCl or user-defined), a digital LCD that displays conductivity and temperature, and data logging for up to 300 data points (value, temperature, date/time); it can also report resistivity up to ~40 MΩ·cm with a high-purity sensor, covers a 0–80 °C range, and offers auto ranging, self-diagnostics, an alarm, and auto power-off. Powered by 2 × AA batteries, it is well suited for field and laboratory use in water treatment, power plants, chemical processing, and laboratory testing for spot-checking water purity, verifying system performance, and troubleshooting process conditions where fixed analyzers are not practical.
