Only the advanced PowerFlex® battery charging system can provide flexibility in charging your fleet of SKC personal air sampling pumps. There is no need to carry multiple chargers for multiple pumps. PowerFlex can be used to charge NiCad and NiMH battery packs for most SKC personal sample pumps (excluding EX and ATEX-approved models and models containing lithium-ion [Li-Ion] batteries). Charge different pump models simultaneously on the PowerFlex five-station charger.
