The HI2315 is a durable benchtop meter that measures conductivity in four different ranges. The meter utilizes a four-ring potentiometric conductivity probe with platinum sensors to offer versatility over typical amperometric designs. By utilizing the four-ring probe, it is possible to measure very low or very high conductivity levels without having to change probes. The HI2315 also offers automatic temperature compensation and an adjustable temperature coefficient (β).
