Sonel Pe6 -

One of the biggest headaches when testing continuity is lead resistance. You twist the probes, press "zero," and hope it stuck. The PE6 uses a 4-wire Kelvin method for continuity testing. This completely eliminates the resistance of your test leads. If you are testing bonding to a water pipe or a rebar in a concrete floor, you get the true micro-ohm reading, not a phantom 0.5 ohms from your leads.

This is not a delicate lab instrument. The Sonel PE6 feels like a brick. It comes in a hard, impact-resistant carrying case with a shoulder strap. The keypad is large enough to use with work gloves on, and the display is high-contrast (usually LCD with a backlight). sonel pe6
