Project Description

Hare Series - Contact Resistance Tester

HARE SERIES Brochure EN

HARE Series is a micro-ohmmeter manufactured by using advanced engineering technologies which can apply up to 100A/ 200A/ 300A test current. With its easy-to-use software, HARE Series can easily measure contact resistance of circuit breaker, shunt and disconnector by applying adjustable test current up to 100A/ 200A/ 300A depending on the model. HARE Series can measure from 0.1 μ Ω to 5 Ω and is capable of measuring static resistance of the circuit breaker’s contact points. HARE Series can also measure idle circuit breakers. The 4.3-inch colour touch screen displays all measurement results on a single screen. With a user-friendly interface, the HARE Series guides operators to perform tests quickly. HARE Series’ flash memory feature allows storing around 1000 records. Users can copy test records by using a USB drive. HARE Series is a very compact, rugged device with IP67 protection class (case closed) which weighs only 3 kg.
