The HI98197 is supplied with a specialized HI763123 four-ring conductivity probe that not only allows for a 0.001 μS/cm resolution measurement but also has screw type threads for insertion into the HI605453 AISI 316 stainless steel flow cell. The HI763123 has a built-in temperature sensor and a adjustable temperature coefficient for accurate readings that cover a complete range with a single sensor. The four-ring technology also eliminates the polarization effect that is common with standard two pole versions. The HI763123 conductivity probe connects to the meter with a unique quick connect waterproof DIN connector allowing for a secure attachment without a threaded connection that is also easy to remove.
