  • Industry standard safety rated at CATIII 600 V/CATIV 300 V



*Important Calibration Information:
This instrument comes with a ‘manufacturer's certificate of conformity’. It is important to understand that this does NOT constitute a ‘traceable calibration certificate’. A certificate of conformity merely states that the equipment has been designed and produced to meet the requirements of its intended application.
Where calibration of an instrument is possible, we will offer this as a separately purchasable item and may be selected from the drop-down box above. You will be sent a full traceable calibration certificate produced in our laboratory and applied with your details as required.

Megger DLRO2 Comes Supplied With:

  • Megger DLRO2 Handheld Low Resistance Ohmmeter
  • 2m Kelvin Clip Test Lead Set (CAT IV 300 10A)
  • 2m Kelvin Probe Test Lead Set (CAT IV 300 10A)
  • 240V Charger Power Supply
  • 6x 1.2V NiMH AA 2000mAHR Batteries
  • USB Memory Stick (with User Guide)
  • Hanging Hook and Strap
  • Soft Pouch

 

Get fast, accurate, repeatable measurements - even in noisy environments - with the DLRO2 hand-held 2 A low resistance ohmmeter. 

The DLRO2 can measure low resistance values across a wide range of applications, from railways and aircraft to industry components. This tough device comes with a brand new ‘difference’ meter that allows repetitive measurements to be easily compared with an initial reference measurement. The difference meter also translates the percentage difference to a needle/pointer movement, making the changes clear to see. 

If your applications require long test leads, then the DLRO2 can provide this without compromising test speed or safety. It has a dedicated long lead test to optimise the output, and this long test lead function is able to provide up to 1 A of test current into 4 ohms resistance. The DLRO2, with its optional cable reel test leads, is therefore ideal for testing wind turbine and avionic lightning protection applications.
