High-accuracy micro-ohm meters up to 600 A for ohmic loads
PROMET R300 and R600 high-accuracy, high-precision ohm meters deliver an adjustable test current of up to 600 A which is independent of the supply voltage. These measuring devices utilize the four-wire resistance measurement method, enabling them to meet the most stringent accuracy requirements. State-of-the-art power electronics coupled with a robust design guarantee excellent reliability for stationary and portable use in switching stations or industrial environments. PROMET ohm meters feature a modern operating concept, an interface to the test systems of the ACTAS product range and external control for use with test stands, making them both flexible and versatile.
