Panoramica del prodotto
The MEGGER DLRO10 bring new standards to low resistance measurement. A fully automatic instrument, selecting the most suitable test current, up to 10 A dc to measure resistance from 0.1 µΩ to 2000 Ω on one of seven ranges.
The DLRO10 is built into a strong, lightweight case that is equally at home in the field or in the laboratory. Light enough to be worn around the neck, they are small enough to be taken into areas which were previously too small to access. DLRO10 uses a large, bright 4-1/2-digit LED display.
