Product Details

JY44A DC Resistance BridgeThe scope of use covers QJ23, QJ44, QJ57 and other single and double arm bridges, digital measurement, built-in rechargeable lithium battery. Suitable for DC resistance measurement of transformers up to 35kV and all transformers; it can also be used for DC resistance measurement of metal conductors, switches, motors, etc. The instrument is small and lightweight, making it an ideal tool for power generation, power supply, and industrial and mining enterprises.

● Instrument measurement range 0～20kΩ

● Maximum output current 10A, suitable for very low resistance measurement of dry-type transformers

● Third-generation power technology, high efficiency, one charge can test hundreds of transformers

● Has inductive test piece anti-disconnection protection function, durable and reliable

● Has audible discharge alarm, clear discharge indication
