Micro Ohmmeter/Ductor Hire

Micro ohmmeters - also known as ductors - can perform resistive, inductive or automatic tests that verify the performance of extremely low resistance conductors found in modern electronics, for example on circuit breakers, switchgear and joints between conductors. Our hire fleet consists of powerful models from Megger Torkel and T&R.
  1. Megger DLRO10HD Low Resistance Ohmmeter w/ DH4-C Test Lead Set


    • High and low power output selection for condition diagnosis
    • Powered by mains or by rechargeable battery
    • Outputs 10A for 60 seconds
    • CATIII 600V safety rating
    • IP54 ingress protection
    • Easy to use

    The Megger DLRO10HD is a battery powered, portable ducter capable of outputting currents of up to 10A. Featuring five user-modes, the DLRO10HD is suitable for a range of applications including routine maintenance checks on HV electrical components and OEM tests.

    With a 10 µΩ resolution and 0.2% basic accuracy, the DLRO10HD can produce quick and accurate measurements. Supplied with 2 x 1.2m length duplex handspike test leads.

  2. Megger DLRO600 Low Resistance Ohmmeter


    • Weighs less than 15kg
    • Test current: 10-600A DC
    • 0.1µΩ max resolution
    • Resistance range: 0.1µΩ to 1Ω
    • Internal memory for 300 results
    • RS232 port for data transfer

    The Megger DLRO 600 Micro Ohmmeter measures resistance from 0.1µΩ to 1Ω via test currents that range from 10A to 600A DC. Resolution is as low as 0.1µΩ which means that the micro ohmmeter can be used for measuring contact resistance on breakers and switchgear as well as for checking cable joint and bus bar connections.

    A large LCD screen shows test results and provides the user with everything he/she needs to execute the test. A handy internal memory can store up to 300 test results with accompanying notes whilst an RS232 port is allows data transfer to a PC or real time printing on a printer.

    The Megger DLRO 600 is compact and lightweight ohmmeter, weighing just 15kg meaning it is portable and does not pose logistical challenges to the user. It constitutes a powerful, versatile ohmmeter for a range of different purposes.

  3. T&R DMO200 Micro-Ohmmeter


    • Test currents from 1A to 200A
    • Measuring range: 0.1µΩ to 5Ω
    • Smooth DC output
    • USB port and memory stick
    • Preset table test currents
    • Weighs just 6.5kg

    The T & R DMO200 can measure resistance from 0.1µΩ to 5Ω with a resolution of 0.1µA thanks to test currents that can be set from 1A to 200A using the instrument’s pre-set current table. Current output is powerful enough to be sent through test leads of up to 20m in length. It is especially suited to measuring resistance in busbar joints but can also measure resistance in substation circuit breakers, isolators and grounding equipment.

    Despite its impressively powerful functionality, the T & R DMO200 only weighs 6.9kg so it is easy to transport. The instrument has a USB port which can accept either a cable to a PC/printer or a memory stick. Normal readings can be given but the instrument also offers a simple PASS/FAIL indication if needed.
