Description

The Simpson Electric 444 is a high accuracy and a high resolution Micro-ohmmeter. The 4½-digit LCD display makes the 444 perfect for testing conductive coatings, high power fuses, and antenna grounding systems. With a test voltage of only 100uV, the 444 will not “punch through” contamination or corrosion. The 444 comes with a test lead with a BNC connector on one end and a Kelvin clip on the other, manual, line cord and Ni-Cad battery for field use.

Features:

• AC pulse or DC polarity switching measurement methods
• Measures from 1 micro-ohm to 20 ohms
• AC lined-powered or battery-powered for lab or field use
• User-adjustable, low-resistance alarm
