High-precision micro-ohm measuring systems with adjustable DC test current for determining resistances on circuit breakers or inductive loads such as transformers, for example. The high-precision ohm meters of the PROMET series are used to determine very low electrical resistances in the µΩ range. The adjustable test current of up to 600 A in combination with a four-wire measuring method delivers measurement results which meet stringent accuracy requirements.
State-of-the-art power electronics coupled with a robust design guarantee excellent reliability for use as a portable device in switching stations and industrial environments. Typical applications include determining the contact resistance of switchgear devices and determining the resistance on inductive loads such as transformers.
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.
