HARE 300

The HARE 300 Micro-Ohmmeter, part of the HARE Series, is a state-of-the-art contact resistance tester designed using advanced engineering technologies. Capable of applying adjustable test currents up to 100A, 200A, or 300A (depending on the model), this device is ideal for measuring the contact resistance of circuit breakers, shunts, disconnectors, and idle circuit breakers. With a measurement range from 0.1 μΩ to 5 Ω, it also accurately tests the static resistance of circuit breaker contact points.

The 4.3-inch colour touch screen displays results in a single, easy-to-navigate interface, guiding operators through test procedures efficiently. The HARE 300’s rugged, lightweight design, with IP67 protection (when the case is closed), ensures durability while remaining portable, weighing only 3 kg. Its flash memory can store up to 1,000 records, and test data can be easily copied via a USB connection.
