Megger All-Purpose High-Accuracy Digital Multimeters

Megger DLRO High Accuracy Digital Multimeters


Megger provides a full service solution to meet your electrical test and measurement needs. Our Megger products provide testing solutions in the most critical maintenance areas including cable fault locating, protective relay testing, on-line monitoring of substation apparatus, and power quality testing. With such a diverse product offering, Megger is the single source for electrical test and measuring instruments.

The Megger range of DLROs of highly accurate, easy-to-operate instruments measure resistance with a resolution as fine as 0.1 micro-ohm. Digital micro-ohmmeters and DLROs measure contact resistance of switch and circuit breakers, aircraft frame bonds, and rail and pipeline bonds and more. Megger has models available for testing using test currents from 0.5 MA to 100 amps covering a multitude of applications that require precise low-resistance measurements

III Megger DLRO100 Series
Megger DLRO1000

Digital Low-Resistance Ohmmeter

The new Megger DLRO100 series offers a unique range of 100 A digital low resistance testers. Never before has CATIV 600 V safety, operational IP54 ingress protection for dust and water, and lightweight, fast charge, Li-ion battery technology been available on a continuous 100 A low resistance tester.

III Megger DLRO10 Series
Megger DLRO10

Digital Low-Resistance Ohmmeter

Probably the smallest, lightest, quickest 10A micro-ohmmeter available. Applications: Switch & contact breaker resistance. – Bus-bar & cable joints. – Aircraft frame bonds & static control circuits. – Integrity of welded joints. -Inter-cell strap connections on battery systems up to 600V peak. – Quality control of resistive components.

III Megger DLRO10X Series
Megger DLRO10X

Digital Low-Resistance Ohmmeter

The Megger DUCTER DLRO10X brings new standards to low resistance measurement. They are fully automatic instruments, 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. For users who desire more control over the measurement process, DLRO 10X uses a menu system controlled by a two-axis paddle to allow manual selection of the test current. DLRO10X also adds real-time download of results and on-board storage for later download to a PC.

III Megger DLRO200 Series

Digital Microhmmeter

The Megger DLRO200-115 measures contact resistance in high voltage circuit breakers, disconnecting switches (isolators), busbar joints, or for any other low resistance measurement. This test set accurately measures resistances ranging from 0.1µΩ to 1Ω at high currents. A versatile instrument, it can provide test currents from 10 amps up to 200 amps, subject to the load resistance and supply voltage. For those applications that demand a smooth DC current, the DLRO200-115 has extra filtering on the output to reduce mains frequency ripple and can drive 200 amps through a total current loop resistance of 11 milliohms. The filtered output of the DLRO200-115 also eliminates magnetic transients that could inductively trip a breaker’s control (bus differential relay), if left in the test circuit.

III Megger DLRO600 Series
Megger DLRO600

Digital Microhmmeter

The Megger DLRO600 measures resistances between 0.1 µohms and 999.9 mΩ, at high currents. This versatile instrument can provide test currents from 10 amps up to 600 amps subject to the load resistance and supply voltage. A large liquid crystal display provides all the information needed to perform a test with all test parameters and measurement results displayed.
