Seaward Cropico DO4002 Handheld Portable Microhmmeter
The highest spec model available in Seaward Cropico's DO4000 series, the DO4002 has a broader measurement range, wider measurement current, and even better resolution than the DO4000 and DO4001.
A portable, easy-to-use low resistance measuring tool, the DO4002 is ideal for porting from test to test as a means of measuring low resistance levels with high levels of accuracy. The unit includes a comprehensive, easy-to-use keypad for easy access to all functions and a large LCD screen for easy reading of your test results.
The measurement range of the DO4002 low resistance ohmmeter is from 4mΩ to 400Ω with resolution as low as 1μΩ and test current at 1A. Measurements are carried out using a true 4 terminal method, eliminating the effects of lead resistance on the accuracy of your testing results.
This instrument also includes several additional features such as auto/manual ranging, open circuit warning and an automatic power-off mode.
