Denver Instrument AP15 pH mV FET Meter w/Charging Dock FREE SHIPPING
Please read our description for complete details.
Available now is this Denver instrument AP15 pH mV FET meter and charging dock. This unit powers up and appears to function as it should, although when the FET probe is plugged in it gives an FET err message, not sure if it is us or the probe needs replaced. This also includes the charging dock and ac adapter but the rechargeable AA batteries have been removed, they can be replaced or it will operate on standard AA's.
