HI 23151

The HI 23151 Bench-Top Multi-Range Conductivity Meter is a multi-range meter with built-in automatic temperature compensation for Conductivity measurements. The HI 23151 replaces EC 215R and features a large, easy to read LCD, solution holders and an attractive redesigned case.          
         
The HI 23151 utilizes a four ring potentiometric probe with platinum sensor that offers greater versatility and accuracy over typical amperometric designs. A potentiometric probe works on the principal of induction which eliminates the effects of polarization (a common problem of amperometric systems). Two outer rings apply an alternating voltage and induce a current loop in the solution while two inner rings measure the voltage drop induced by the current loop (which is dependent on the conductivity of the solution). By utilizing the 4-ring method, it is possible to measure very low to high conductivity levels (up to 200 mS/cm) without changing probes.         
         
The temperature coefficient correction is adjustable from 0 and 2.5%/°C.
