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

Augmenting Megger’s Ducter™ range of 10 A micro-ohmmeters, the DLRO10HDX combines ultimate simplicity of operation with a rugged IP65 case designed for stable ground and bench operation and provides memory storage.

These units are powered from either rechargeable battery or mains power making it suitable for continuous testing in production line/repetitive use environments.

Rotary switch controls are simple and easy to operate in all weather conditions and with gloved hands. A large, clear, backlit LCD display is easy to read from a distance. The DLRO10HDX provides significantly enhanced compliance and is capable of delivering 10 A into measurements up to 250 mΩ and 1 A into measurements up to 2.5 Ω. The duration of each test may be up to 60 seconds.

The DLRO10HDX is rated CAT III 300 V provided the optional terminal cover is fitted to the instrument.

History of ‘Ducter’ testing
For over 100 years the ‘Ducter test’ has been used to describe a simple test for measuring very low contact resistances and “Ducter”, which is still used as a trade mark, was the name originally given to the low resistance ohmmeter manufactured by Megger. The name Ducter was registered by Megger in June 1908 and ‘Ducter’ has since become the industry standard.

• Onboard memory storage for test results up to 200 records (HDX only)
• Download to PowerDB
• Interchangeable test lead terminations
• High or low output power selection for condition diagnosis

The BALTO Compact System was developed to generate, and inject into the circuit, very high and precise DC test currents in order to carry out functional tests on high-speed DC circuit breakers. The problems that arise during the testing of high-speed DC circuit breakers frequently worry service and maintenance personnel, especially when it comes down to checking and adjusting the thresholds. The BALTO Compact has been developed specifically for testing DC high-speed circuit breakers at rolling stock, tramways and primary infrastructure. It is also suitable for on-board maintenance in marine applications. Special attention was given to the weight and size of this compact version resulting in an ergonomic design that permits usage in small spaces.

• Ergonomic design
• Energy sources: batteries and ultra-caps
• Power units: DC/DC current converters- Internationally patented
• Current rate of rise can be adjusted

The BALTO System was developed to generate, and inject into the circuit, very high and precise DC test currents in order to carry out functional tests on high-speed DC circuit breakers. The problems arising during testing of high-speed DC circuit breakers frequently worry the service and maintenance personnel of rail-way organisations, especially when it comes down to checking and adjusting the thresholds. To meet the requirements encountered in the market, the innovative BALTO system was subject to the specifications worked out on the basis of requests from high-speed DC circuit breakers’ manufacturers and various railways/train operators and public transport companies.
