Seaward Cropico DO4001 Handheld Digital Microhmmeter with Temperature
Measure low resistance levels with a high level of precision with the Seaward Cropico DO4001, a portable, handheld unit for use anywhere you need to test low resistance.
This is the upgraded version of the Seaward Cropico DO4001. Both models have similar functionality and measurement capabilities, except this model also includes automatic temperature compensation and temperature measurement capabilities.
Highly precise, the DO4001 can measure low resistance levels from 40mΩ to 4kΩ with resolution as low as 10μΩ. This handheld, portable microhmmeter is ideal for use in a wide variety of applications ranging from aerospace to automotive and utility environments.
This unit also includes several additional features such as auto/manual ranging, true 4 terminal measurements to eliminate lead resistance and compatibility with a wide variety of optional test leads to cater for use in different areas (see below for available accessories).
