Innovative Sensor Technology LFS Series Conductivity Sensors
Innovative Sensor Technology LFS Series Conductivity Sensors operate in a wide conductivity and temperature range and feature a four-electrode measurement configuration and a Pt1000 temperature sensor. The LFS sensors provide a fast response time, long-term stability, and resistance to various chemicals, with a conductivity measuring range of 10μS/cm to 200mS/cm. IST LFS Series Conductivity Sensors are ideal for measuring ionic content for water purification and abatement, monitoring membrane processes separating ionic compounds, and more.
