Yokogawa SC42-SP24 | SC4A Conductivity Sensor

Overview

The Yokogawa SC42-SP24 Conductivity Sensor is a high-precision sensor designed for a wide range of industrial process applications, including ultra-pure water environments. Constructed with stainless steel (AISI 316L) and PEEK, this sensor ensures durability, reliability, and resistance to harsh conditions.

The SC42-SP24 sensor is equipped with a built-in Pt1000 temperature element for automatic temperature compensation and features a pre-calibrated cell constant. It is also certified for hazardous areas when connected to a certified intrinsically safe Yokogawa analyzer (SC202S, FLXA-series) or a certified intrinsically safe circuit.
