Electrode impedance meter with active and reference lead

The 505665-Electrode Impedance Meter (Optional)  is an electrode resistance meter designed to complement the SU-BV-10 electrode beveler. Resistance is indicated by a precision analog meter, which allows the user to easily identify changes in microelectrode resistance while beveling.  Each meter is calibrated using the active lead that is shipped with the meter. Use of another cable, even if it is from another impedance meter or SU-BV-10 meter, may require recalibration to produce an accurate reading.
