RET-МОМ is an instrument with no analogs as it combines the functions of two instruments - the microohmmeter and the milliohmmeter.
Thanks to this, it is possible to measure a wide range of resistances: from automate contacts to high-inductance power transformer windings:
in "microohmmeter" mode within 1 µΩ ... 100 mΩ range:
in "milliohmmeter"mode within 1 mΩ ... 200 Ω range you measure:
Due to the high output power RET-МОМ supports up to 600 A injection. This is utmost important when measuring small resistances. Therefore, an incredibly high measuring accuracy is obtained. Besides, high current and power values make it easy to measure resistance of contact or welded, bolt joints covered with the protective layer or that are dirty.
Due to the function "BOOST" that enables fast and, most important, secure winding magnetizing and de-magnetizing, RET-МОМ saves time considerably when measuring the power transformer winding resistance.
Besides, RET-МОМ performs many things automatically, videlicet:
RET-МОМ provides advanced disturbance immunity and supports operation in most severe climatic conditions with the temperature -20 ... +50° С
