Who makes cheapest 4-wire ohmmeter?

Who makes the least expensive ohmmeter or DMM with a 4-wire (or “Kelvin”) resistance measurement?

If you’re wondering, a 4-wire resistance measurement uses 2 wires to pass a current through the resistance and 2 other wires to measure the voltage drop across it. This completely ignores the resistance in the test leads, so they can have a million or more times the resistance of the device under test and not interfere. This is most important for measuring low resistances of, say, less than an ohm, or certainly less than a 10th or 100th.

Napier: The “four-wire resistance measurement technique” should be used when measuring a resistance under approximately 1000 Ω. If I were you, I would try to find an HP 3478 on the used/surplus web sites. If you’re bent on purchasing something new, I would peruse this web site. They sell a variety of new test equipment at rock-bottom prices. But in all honesty, a used HP 3478 or 34401A will be a lot better than a “new” Asian-made DVM such as those sold by Web-Tronics.
