Resistance Measurements

Compact micro-ohm meter for ohmic and inductive loads

PROMET L10 is a compact, battery-operated micro-ohm meter for ohmic and inductive loads.
The use of four-wire measuring technology and high test currents of up to 10 A enable PROMET L10 to meet the most stringent accuracy requirements when determining resistances in the μΩ to kΩ range.
Because PROMET L10 can carry out measurements on inductive loads, it can also be used to determine the winding resistances of transformers, motors and instrument transformers.
Not only does the device provide high functionality, its light weight of just 0.6 kg, rechargeable batteries and operation via Android app also make it suitable for a wide range of applications.

  1. Light weight for one-handed operation
  2. Easy to use
  3. Graphical display and acoustic signalling
  4. Battery operation for up to 8 hours
  5. Measurements on inductive loads
  6. Measurements on ohmic loads
  7. Measurements with temperature compensation
  8. Wide measuring range
  9. Operation via Android app
