Product Overview

The GOM-805 from GW Instek is a DC milli-ohm meter. This modern high precision programmable DC milli ohm meter is suitable for low resistance measurements of switches, relays, connectors, PCB tracks and a variety of other devices. It features a colour TFT-LCD screen with easy-to-read measurement results. With the easy to use features, superior performance and automatic test interfaces this meter is dependable instruments for resistance measurements. Each test function on the can be easily activated by pressing a single front panel key. All settings and measurement results are displayed and set on the TFT-LCD panel at the same time making each function naturally intuitive to use. It has nine selectable measurement ranges from 50mohm to 5Mohm, a constant current source of 1µA to 1A, up to 0.05% accuracy, 1µohm resolution and performs measurements using four wire Kelvin connections for accurate, consistent measurements. It is used incoming inspection and quality assurance testing.
