Amprobe PM55A Pocket Multimeter with VolTect Non-Contact Voltage Detection
A credit-card-sized pocket digital multimeter with permanently attached test leads that measures AC and DC voltage to 600 V, microamps to 2000 µA, resistance, capacitance and frequency, plus built-in non-contact voltage detection.
Selected package: Amprobe PM55A auto-ranging pocket multimeter.
Model: PM55A
These are different products. Check their specifications separately.
Manual-ranging, fewer functions and a lower count; the maker positions it as the simpler sibling of the PM55A.
Basic DC voltage and continuity checks on a tight budget.
