QJ44 DC Double Bridge

QJ42 DC Double Bridge is portable DC resistance bridge, which is designed based on Kelvin bridge circuit. This instrument is provided with built-in null-indicator and internally attachable power supply, so that it is suitable to be used in industrial laboratores, and out door sites to make precise measurement to DC low resistance. For example it can measure the conductivity of metals, the winding resistance of electric mkotors and transformers, and the contact resistance of electric-brushes and switches. They also can be used to carry out temperature elevation test, and so on.
