Clarkson EC215R-02
Multi-range Conductivity Meter with Analog Output 230V
Hanna Instruments EC 215R-02
Description:
Four measurement ranges
Manual calibration
Automatic Temperature Compensation
Analog output
This instrument utilizes a four ring potentiometric probe with platinum sensor that offers
greater versatility 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 or high conductivity levels (up to 200 mS/cm) without changing probes.
The temperature coefficient correction is settable between 0 and 2.5%/ºC.
In addition, EC 215R offers analog output of 0 to 5V that represents the full conductivity scale across all four ranges.
