Product Description

JY44A DC Resistance Bridge

Darui Electric recommends:

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

● 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

● Inductive test anti-disconnection protection function, durable and reliable

● Audible discharge alarm with clear discharge indication
