This reading is very important when counseling patients about battery life expectancy, determining how long a hearing aid battery will last, or evaluating a problem instrument. Simply plug in the hearing aid, turn the unit on and battery drain is instantly displayed. The BDM-2 unit also includes a voltage probe for conveniently measuring DC voltage. A must for any hearing aid technician. 120 volt, 60 Hz. Battery pills not included. With Voltage Probe.
