The Power Probe DM500MAX Digital Multimeter is designed for accuracy and measurement reliability. Built for even the harshest work environments, the tool contains watertight gaskets at the seams, a rotary switch, input terminals, and a battery cover to keep out dust, dirt, and moisture. The DM500MAX can survive falls and drops with its outer housing protector and includes a LoZ(low impedance) mode to prevent false readings caused by ghost voltages. Additionally, it has a backlit 40,000 count, extra-large digital display, a 40,000 records data logging capacity, and is CAT IV 600V/CAT III 1000V rated. It comes with a case, test leads, and all accessories like a temp probe and magnetic hanging strap.
