The Amprobe PM53A digital multimeter is a shirt-pocket sized meter, just 3/8" thick and weighing less than 3 ounces. Despite its small size, the PM53A offers full functionality with AC and DC voltage to 450 V, resistance to 6 MΩ, capacitance to 100 µF, frequency to 30 kHz and continuity with beeper. The Amprobe PM53A also offers VolTect, a built-in, non-contact voltage detection for AC voltages.

A key feature of the Amprobe PM53A digital multimeter is AutoTect, which automatically selects AC voltage, DC voltage or resistance measurement based on the test point to which the leads are connected. Fully autoranging, this meter offers seven different measurement functions plus features that are usually found in much more expensive and larger meters.

The digital display is oversized with large digits and unit icons in the display. The PM53A is fully safety rated to CAT III 300 V, CAT II 450 V and is UL approved.
