The Ballantine 4-1/2 Digit Micro-ohm Meter 3207 measures Low Resistance in Milli and micro-ohms with
precise accuracy. It employs the proven 4-wire measurement technique and eliminates the lead resistance
inherent in 2-wire technique to give accurate readings.

Applications:
Cables, Components, Skin and Frame Bonds, PC Boards, Bus Bars &
Contactors, Electrodes, Motors & Transformers Systems

Features:
    • 4-1/2 Digit LED Display
    • True 4-Wire Measurement Technique to Eliminate Lead Resistance error
    • Pulse Mode Operation for Basic Accuracy of 0.05%
    • Rechargeable Internal Battery-Optional
    • 2 milli-Ohm to 2000 Ohm Full Scale Ranges
    • Resolution to 0.1 micro Ohm on 2 milli-Ohm Range
    • RS-232 PC Interface
