Micro-Ohmmeter MOM2

New patent pending technology has made MOM2 small and light, it weighs about 1 kg. Despite the small size and light weight the instrument can deliver a maximum current of about 220 A short duration and up to 100 A for three seconds. With MOM2 it is possible to make the test according to the DualGround method. This means that the test object remains grounded on both sides throughout the entire measurement procedure.


Micro-Ohmmeter MJÖLNER 200

The MJÖLNER 200 has been designed with safety, easy of use and versatility in mind. This micro-ohmmeter can be used anywhere requires to measure a low resistance value. The lightweight of 8.8 kg and rugged suitcase makes MJÖLNER 200 an excellent choice when you need a portable solution in the field. Output 5-200A DC.



Micro-Ohmmeter MJÖLNER 600

The MJÖLNER 600 has been designed with safety, easy of use and versatility in mind. This micro-ohmmeter can be used anywhere requires to measure a low resistance value. The lightweight of 13.8 kg and rugged suitcase makes MJÖLNER 600 an excellent choice when you need a portable solution in the field. Output 5-600A DC.





Micro-Ohmmeter MOM690

Measuring resistance is an important part of maintaining high-voltage breakers and disconnecting switches. Instruments that measure the resistance of high-current contacts and other transmission elements have been included in the Programma line of products for many years. MOM690 supplements our family of microhmmeters. In addition to high current capacity, MOM690 features microprocessor-based measurement, storage and reporting.

Micro-Ohmmeter MOM600A

Switchgear breakdowns are frequently caused by excessively high contact resistance at breakpoints and busbar joints. Moreover, overheating risks are becoming more serious due to the fact that today's distribution networks have to carry heavier loads. Checking contact resistances at regular intervals detects faults before they cause overheating. And here, an ounce of prevention is worth a pound of cure. Microhmmeters are used to measure contact resistances in high-voltage breakers, disconnecting switches (isolators), knife-contact fuses, bus joints, line joints etc.

Micro-Ohmmeter MOM200A

Like the MOM690 and MOM600A, this model is designed to check and measure contact resistances in highvoltage circuit breakers, disconnecting switches (isolators) and busbar joints. The MOM200A is an excellent choice when 200A DC or less are needed for measurement. MOM200A is ideal for finding poor connections since it can put out 100 A for extended periods. Its range extending up to 20 milliohms makes it ideal for measuring many different types of connections. See also Mjölner 200 on this page.
