Set of four Ni-Cad batteries, designed for use with the Fluke ScopeMeter 120 Series and Fluke-43B Power Quality Analyzer. The battery pack has to be charged in the instrument. Performing refresh cycles on a regular basis, as provided by the 120 Series ScopeMeter, will strongly contribute to the lifespan of the batteries. The battery capacity is 3000 mAh, this is 50% more than that of the original BP120. As a result, the instrument-user will benefit from a much longer 'up time' than with the original NiCd battery, at the same volume and weight. The BP120MH is more environmental-friendly than the NiCd battery used before, as it contains no heavy metals. Just as before, the battery pack can be charged while installed in the instrument, using the PM8907 power adapter/charger. The BP120MH replaces the earlier models BP120 and BP130 alike.
