Hanna EC 215 Mutti Range
HANNA EC215 Multi Range Conductivity Meter w/ Temp.
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
The Hanna EC215 is a multi-range bench top conductivity meter with four measurement ranges to ensure the highest resolution and accuracy to meet your measuring requirements.
Calibration is performed manually using 1-point simply by adjusting a knob on the front of the meter. With a user selectable temperature coefficient and a temperature sensor incorporated in the probe, temperature compensation of the reading is automatic.
Included with this meter is the fast responding HI 76303 probe. This probe is equipped with a 4-ring platinum sensor, built-in internal temperature sensor and a 1 m long cable, which can be used for measuring highly acidic or alkaline samples.
The EC215 is supplied complete with HI 76303 probe with internal temperature sensor and 1m long cable, 12 Vdc adapter and instructions.
