Upgrading from RM15 to RM15-D Resistance Meter

The earlier RM15 instrument has now replaced by the RM15-D instrument but it is possible to upgrade older instruments to this newer version. Please contact Geoscan Research for details.

The RM15-D has an internal detector that can distinguish between the special NiMH battery pack provided and the alternative alkaline battery holder. The RM15-D will only recharge the special NiMH battery pack - alkaline batteries cannot be charged. This will prevent the possibility of alkaline batteries being charged by mistake which can cause the battery to leak and damage internal electronics resulting in expensive repairs.
