PROMET 100 / 200 / 600
High-accuracy, versatile micro-ohm meters

PROMET 100 / 200 / 600 high-accuracy, precision ohm meters deliver an adjustable test current up to 600 A which is independent of the supply voltage. They utilize the four-wire resistance measurement method, enabling them to meet extremely stringent accuracy requirements when determining resistance values in the micro-ohm range.

State-of-the-art power electronics coupled with a robust design guarantee maximum reliability, even when used as portable devices in switching stations or industrial environments.

The modern operating concept, an interface to the test systems of the ACTAS product line and an optional remote control unit make these micro-ohm meters flexible and versatile. 

PROMET SE - High-accuracy, compact micro-ohm meter

PROMET SE is a compact, battery-operated ohm meter with an adjustable test current of up to 200 A. Two current outputs and two voltage measurement inputs allow the resistance to be determined at two measurement points simultaneously.

Flexible handling with battery operation and the high functionality and precision which are characteristic of the popular PROMET product range make this universal micro-ohm meter particularly suitable for portable use in switching stations or industrial environments.

Four-wire measuring technology enables PROMET SE to meet the most stringent accuracy requirements, making it ideal for the high-precision determination of resistances in the micro-ohm range.


High-accuracy micro-ohm meter for ohmic and inductive loads
PROMET SMO is a compact, battery operated, high-precision measuring device for determining resistance values in the micro-ohm range. The use of four-wire measuring technology and high test currents of up to 100 A enable PROMET SMO to meet extremely stringent accuracy requirements. This micro-ohm meter can also be used to determine the winding resistances of transformers, motors and instrument transformers.
High functionality, rechargeable batteries and a light weight of just 9.3 kg make this measuring device suitable for universal use.
