CROPICO DO7 MICROOHMMETER

The Cropico DO7 is a robust and portable digital microOhmmeter with protection up to 415 Vrms in a lockable ABS housing. The four-wire connection eliminates measurement errors caused by the resistance of the connecting leads. Further features are digital calibration and an accurate reading. The measuring range runs from 600 µΩ to 60 Ω and the resolution is 0.1 µΩ in the lowest range. The internal battery makes it possible to measure with 10 A in the lowest range without an external power supply. In the lowest range more than one hour of continuous operation can be performed on the battery, in the other ranges 20 hours.

The DO7 has a microcontroller that offers the best measurement, reliability and capabilities. Autoranging, forward and reverse current measurements with auto average and remote start socket are built in as well as battery saving power down.
