Megger BT51 2A Low Resistance Ohmmeter (6410-091)

Providing quick and easy measurement of low resistance levels, the Megger BT51 2A Low Resistance Ohmmeter is ideal for everything from testing earth bonds in minds to evaluating resistance on switches, circuit breakers and more.

Passing current through the conductor under test and also monitoring the voltage across it, the Megger BT51 limits the current so the voltage can be measured and ensuring that the accuracy of the reading remains unaffected by current variation. For added accuracy, the BT51 also utilises four-terminal testing, filtering out the resistance of test leads.

Offering two measurement ranges and a 2A nominal test current with up to 2Ω across C terminals, the Megger BT51 is also protected against 240V AC and features warning lights for extra safety.

With a 3 ½ digit LED display and an incredibly robust design ensuring it’s shockproof and weatherproof, the BT51 Low Resistance Ohmmeter is perfect for use in most environments. It comes supplied with a battery charger, two spring-loaded duplex hand spikes, and a two-wire DH1-C duplex twist probe lead set as standard.
