200 A micro-ohmmeter

The MOM200A is designed to check and measure contact resistance in high voltage circuit breakers, disconnecting switches (isolators), and busbar joints. This unit is an excellent choice when 200 amperes or less are needed for measurement.

• Measures contact resistance in circuit breakers, disconnecting switches, busbar connections, safety devices, etc.
• Easy to operate
• Designed for rugged field use
• Highly flexible cable connections
• Portable and lightweight, weighs only 14 kg (31 lbs)

2 A Low resistance ohmmeter

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.

• New Difference Meter for quick data comparisons 
• Use long leads at 1 A without compromising test speed 
• Safely test the resistance of inductive loads at 1 A 
• < 600 V active protection against inadvertent live connections without blowing a fuse 
• Ideal for outdoor use with protection against dust and moisture to IP54 
• Industry standard safety rated at CATIII 600 V/CATIV 300 V
