The Improved Raytech Micro Junior II DLRO

  • Uncategorized

Rusty terminals or carbonized contacts can reduce the efficiency of electrical components in a power system. A digital low resistance ohmmeter is a test device that measures the resistances of bonded metals, relay contacts, electrical terminals or any metal in contact with another metal. An increase in resistance on these devices can be a sign of degradation.


The Raytech Micro Junior II is a high precision DLRO or contact resistance meter that has a maximum output current of 10 amperes. It has 5 current ranges with a resistance range from 0.1 micro ohms up to 400 kilo ohms. It also has a RS232 serial port so the device can be attached to a computer for enhanced features. Its LCD panel has a back lighting system so that you can read the results even on a poorly-lit environment. You can store up to 2000 test results in its built-in memory storage and recall it at a later time. It has an integrated printer which gives you the option to print the test results. With its rugged construction and waterproof case, it can withstand harsh working environments.
