PCE Instruments PCE-MO 2002 Milliohmmeter

Overview

The PCE Instruments PCE-MO 2002 is a digital milliohmmeter designed for precise resistance measurements in the milliohm to kiloohm range. Featuring a four-conductor measurement system with alligator clips, this robust device measures from 100 microohms up to 2000 ohms and is housed in a ruggedized, waterproof carrying case. The PCE-MO 2002 applies a constant current to the measured object and tests the resulting voltage drop, making it ideal for testing connections, continuity, and electrical contacts across industrial and domestic applications.
