444-2 Micro-Ohmmeter

High accuracy and a high resolution 4-1/2 digit LCD display make the 444-2 perfect for testing conductive coatings, high power fuses, and antenna grounding systems. With a test voltage of only 100 MicroVolts, the 444-2 will not “punch through” contamination or corrosion. The 444-2 accepts the Universal AC Line input Voltage range of 85 to 250VAC and comes with a manual, Line Cord, Ni-Cad battery, and 2 test leads. Each test lead incorporates a BNC connector on one end and a Kelvin clip on the other.
