QJ57 dc bridge
 

Brand: Shanghai star Yue

Transistor is added inside this instrument enlarge is galvanometric and can inside add working power source. Agree with industrial and mining enterprises, lab or workshop spot and fieldwork place make what dc block measures use. Lead with the resistor that will measure conductor of the dc block inside its limits, metal, the resistor winding a string of the osculatory resistor of lead resistor, dc spreader resistor, switch, electric equipment and of all kinds electric machinery, transformer and temperature rise experiment.
