The DM500MAX is designed for harsh environments with a watertight gasket as the seams rotary switch, an input terminal, and battery cover to keep out dust, dirt, and splashing fluids. The meter can also take shocks and drops, work anywhere from indoor to outdoor, and special designed LoZ(Low Impedance) feature to prevent false reading caused by ghost voltages. A magnetic strip on the backside provides a stable position and also comes in handy when storing it.
