The MEGGER DLRO10 Micro Ohm Meters 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 0.1µΩ to 2000 Ω on one of seven ranges.
The DLRO10 Micro Ohm Meters 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. DLRO 10 uses a large, bright 4-1/2-digit LED display.
The MEGGER DUCTER DLRO10 and DUCTER DLRO10X Micro Ohm Meters bring new standards to low resistance measurement. Both are fully automatic instruments, selecting the most suitable test current, up to 10 A dc to measure resistance from 0.1µΩ 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 Micro Ohm Meters also adds real-time download of results and on-board storage for later download to a PC.
Both instruments are 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. DLRO 10 uses a large, bright 4-1/2-digit LED display while DLRO 10X has a large, backlit LCD display.
Equally at home in the laboratory, the workshop or in the field, on the bench or on the ground, Megger’s new heavy duty DLRO10HD low resistance ohmmeter combines rugged construction with accuracy and ease of use. It features an internal rechargeable battery and can also operate from a mains supply, even if the battery is completely flat.
Megger DLRO200 Micro Ohm Meters measures resistances between 0.1µΩ and 1Ω, at high currents.
This versatile instrument can provide test currents from 10 amps up to 200 amps subject to the load resistance and supply voltage. A large LCD displays all all test parameters and measurement results.
Megger DLRO600 Micro Ohm Meters measures resistances between 0.1µΩ and 1Ω, at high currents.
This versatile Micro Ohm Meters 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; all test parameters and measurement results are displayed.
The unique design allows the weight and size of DLRO600 Micro Ohm Meters to be kept to a minimum; the instrument weighs less than 5kg. This small size makes DLRO600 equally at home in the workshop, on the production floor or in the field. The high current capability and compact design make DLRO600 suitable for testing circuit breaker contacts, switch contacts, busbar joints or other applications where high current is needed.
Megger Digital Low Resistance Ohmmeters (DLRO) are a family of highly accurate instruments that provide a simple, practical and reliable means of making low-resistance tests in the field. They also are ideal for production quality control. They operate on the four-wire measurement principle, thus eliminating lead and contact resistances. With basic accuracies of ±0.25% and resolution down to 0.1µΩ they are nonetheless designed to be rugged and portable for use at the job site.
The risk of overheating is becoming more serious due to the fact that today’s distribution networks have to carry heavier loads. Checking contact resistances at regular intervals detects faults before they cause overheating.
Microhmmeters are used to measure contact resistances in highvoltage breakers, disconnecting switches (isolators), knife-contact fuses, bus joints, line joints etc.
The MOM2 Micro Ohm Meters is designed to measure the resistance of circuit breaker contacts, bus-bar joints and other high-current links. This product is designed with safety, ease of use and versatility in mind.
MOM2 Micro Ohm Meters uses an ultra capacitor to generate the high output current. The ultra capacitor is able to store a huge amount of energy compared to conventional capacitors and can deliver very high current during the discharge thanks to its very low internal resistance. The microhmmeter can be used anywhere to measure a low resistance value with high accuracy.
With MOM2 Micro Ohm Meters it is possible to make measurements according to the DualGround™ method. This means that the test object will be grounded on both sides throughout the test giving a safer, faster and easier workflow.
MOM690™ Micro Ohm Meters supplements our family of microhmmeters. In addition to high current capacity, MOM690™ features microprocessor-based measurement, storage and reporting. The built-in software enables you to carry out an individual test or an entire series of tests and store the results.
With the optional MOMWin™ software you can also export the test results to a PC for further analysis and reporting. Ranges are set automatically, resistances are measured continually and test results can be automatically captured at a preset test current.
The MOM200A Micro Ohm Meters is designed to check and measure contact resistances in highvoltage circuit breakers, disconnecting switches (isolators) and busbar joints. This unit is an excellent choice when 200 amperes or less are needed for measurement.
The BT51 Low Resistance Micro Ohm Meters makes measurements by passing a current through the conductor under test and also monitoring the voltage across it. The test current is limited by a simple current limiting circuit and is measured by monitoring the voltage across a resistor. The test current is maintained at a nominal 2 A, and as the measurement is ratiometric, the reading is unaffected by any current variations.
