Conductivity is a core indicator reflecting ion concentration in water, widely adopted for real-time water quality monitoring in municipal, industrial and civilian water treatment fields. ACITEK CR-GS-10 is a platinum two-electrode conductivity sensor with cell constant K=10, one of the three mainstream series (GT graphite type, EC stainless steel integrated temperature type, GS platinum electrode type) of ACITEK conductivity probes. With wide measuring range, stable performance, flexible installation and cost-effective design, this sensor delivers reliable conductivity detection under -5~+80°C and maximum 6 bar working pressure, perfectly matching routine water quality measurement demands across multiple industries. This article systematically sorts out its core application scenarios, matching advantages and practical application values.
