Seaward Cropico DO7e Low Resistance Digital Micro Ohmmeter
Looking for a reliable, portable method of testing low resistance levels? You need the Seaward Cropico DO7e.
Built inside its own tough carrying case for easy transportation, you can use this low resistance ohmmeter in a wide variety of applications ranging from aerospace to automotive and military environments.
The DO7e delivers highly accurate results thanks to its true 4 wire measurement technique, effectively eliminating lead resistance which can affect measurements. It can test low resistance levels across 6 ranges from 6mΩ to 600Ω (it's auto ranging and will select the appropriate range as needed) and can use up to 10A measurement current (when measuring on the lowest range). The DO7e can perform forwarvd and reverse current measurements (with automatic average) and displays all results on the daylight-visible LED display built inside the case.
This low resistance ohmmeter can either be powered by connection to the mains or by rechargeable batteries. Battery life is greater than 1000 measurements (on lowest 10A range) or up to 20 hours on other ranges when fully charged.
Additional features of the Seaward Cropico DO7e includes automatic power off, digital calibration pass code protection and input protection up to 415V rms.
