Handheld Micro-Ohmmeters
RMO-H Series
-
The RMO-H is battery operated and handheld micro-ohmmeter. It is designed for a variety of applications for contact resistance measurement of non-inductive test objects. Typical applications are accurate testing of:medium and high-voltage circuit breakers,disconnecting switches,high-current bus bar joints,cable splices,and different high-current links.Even more, it accurately measures in high-induction filed environments and substations, as well as in factory testing.RMO-H Series contains six models in total, divided in 2 sub-series depending on the test leads length requirement and the battery type:RMO-H1, RMO-H2 and RMO-H3 models are intended for use with short cables (e.g. 1,3 m / 3 m / 5 m). The 1-cell Li-Po battery with 8200 mAh capacity provides output voltage up to 4,1 V DC.RMO-H21, RMO-H22 and RMO-H23 models are ideal for applications where test leads with lengths > 5 m are required. The high output voltage (up to 8,3 V DC) is provided by 2-cells 4100 mAh Li-Po battery.The test current is regulated and can be selected in a range of 1 A to maximum 300 A, depending on the maximum test current rating:RMO-H1, RMO-H21 models – up to 100 A DCRMO-H2, RMO-H22 models – up to 220 A DCRMO-H3, RMO-H23 models – up to 300 A DC.Unlike many other handheld micro-ohmmeters available on the market, our instruments have regulated and user-selectable test currents. Therefore, RMO-H instruments generate an automatically regulated test ramp with stable and ripple-free current during measurement. These revolutionary characteristics in a handheld micro-ohmmeters technology are possible by using sophisticated Li-Po batteries. Consequently, modern battery technology enables you to do multiple measurements, and a full day of testing without recharging the battery.With all RMO-H models, it is possible to make tests on Both Sides Grounded testing objects, in an increased safety environment. Finally, these features in combination with a user-friendly interface (1-click to measure) significantly speed-up testing procedure and make it safer.These instruments store up to 1000 measurements on the internal micro SD card.Our free DV Win software communicates with the RMO-H micro-ohmmeters via a wireless Bluetooth interface. Furthermore, it allows you to download test results, analysis and generate fully configurable test reports.

Contact Resistance Tester
JYL
-
As a high current passes through a pair of mechanically independent metallic contacts, the contact resistance must be as low as possible. Increasing the contact resistance of the contact often causes a large voltage drop on the contact, which reduces the input power of the load equipment. If the contact resistance of one or two contacts becomes large, the three-phase voltage of the load equipment will be unbalanced, causing phase loss operation.

Contact Resistance Meter
CRM 200B+
-
CRM directly measures micro-ohm values at 200A DC under live EHV switchyard conditions quickly & accurately. It is specially designed to reliably measure micro-ohm contact resistances of Circuit Breakers, Isolators, Busbar joints, earth switch joints, welded joints etc., under the hostile electrostatic noise found in live EHV switchyards up-to 765 kV. SCOPE’s ability to make electronics work in such environment enables CRM to measure mili-volts signal in the presence of kilo-volts noise.
