    Microohmmeter
    MMR-6700
    Versatile and multifunctional micrometer Sonel MMR-6700 - a single device for HV circuit breaker and transformer measurements. It is distinguished by a modern design and advanced solutions enabling measurements of resistive objects with high current. Additionally, the device has a module for measurement of inductive objects with current up to 10 A, which is a distinctive feature of MMR-6XXX series and a unique solution in its class.

    Microohmmeter
    MMR-6500
    It is distinguished by a modern design and advanced solutions enabling measurements of resistive objects with high current. Similarly to other models of MMR-6XXX series, this device has been equipped with a module for measurement of inductive objects with current up to 10 A, which is a unique feature among meters in this class. Its practical functions - temperature measurement and automatic compensation of measurement results in relation to the temperature measured or programmed by the user - are worth highlighting. The MMR-6500 also has recorder functions.

    Micro-ohmmeters
    MMR-650
    Ready to work even in extreme conditions, the winding resistance and small resistance meter Sonel MMR-650 has been created to accurately measure small resistances of resistive and inductive objects. The instrument can be used to measure the resistance of both transformer windings - including amorphous-core transformers - and resistive objects. The MMR-650 meter is dedicated to use in power plants, maintenance companies and railway industry, among others.

    Microohmeters
    MMR-630
    We present a versatile small resistance meter that provides very high measurement accuracy. The measurement resolution is 0.1 µΩ. The MMR-630 model enables measurements of objects of resistive as well as inductive nature, such as transformers and motors. This is due to the large measurement current for the individual subranges and the corresponding operating modes. When testing objects of a resistive nature, rapid measurement (3 seconds) is applicable. When testing inductive objects, extended measurement is used (there is also the possibility of a shortened mode with a slightly lower measurement accuracy).

    Microohmmeter
    MMR-620
    We present a professional small resistance meter MMR-620, which ensures high measuring accuracy - the measurement resolution is 1 µΩ. With the use of this device it is possible to perform measurements of objects of both resistive and inductive nature (e.g. testing of transformers or motors). The meter provides a high measuring current for individual subranges and various operating modes, adjusted to the type of measured object - quick measurement mode (3 sec) for testing objects of resistive nature, as well as extended measurement mode for testing objects of inductive nature.
