Cropico DO7e

The Cropico DO7e is a practical, low-cost micro ohmmeter designed for precise low resistance measurements. It is ideal for use in utilities, workshops, field service, or test facilities.

Housed in a rugged, sealed ABS plastic case with lid and carrying handle, the DO7e combines portability with durability. It features advanced digital calibration, a long 6,000-count scale length, and automatic or manual range selection. An automatic power-off function maximises battery life, while the internal charger provides rapid boost charging with automatic switch to trickle maintenance charge.
