MMR-6700
Measure HV switches and transformers with one device
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.
The Sonel MMR-6700 has been enhanced with many useful functions, such as temperature measurement and automatic compensation of measurement results in relation to the measured or user-programmed temperature. The micrometer also has a recorder function. Due to special measurement algorithms and additional functions, the Sonel MMR-6700 allows you to select the appropriate measurement method depending on the nature of the measured object and the measurement conditions, thus increasing the measurement capabilities and application areas of the device. The meter's functionality is complemented by a modern, easy-to-read interface, a range of communication interfaces, wireless communication and cooperation with a computer, printer and a 2D code reader. All these features make Sonel MMR-6700 a convenient and intuitive way to manage measurements, their results and identification data of measured objects.
