The pioneer of qj36 dual-purpose DC bridge strength
The qj36 dual-purpose DC bridge is a precision electrical measuring instrument. The qj36 dual-purpose DC bridge is used to measure the conductor resistance. The precision level is 0.02. The qj36 dual-purpose DC bridge adopts different linking methods to form a single bridge. And double bridge two kinds of measurement circuit. The qj36 dual-purpose DC bridge can measure DC resistance in the range of 0.000001Ω~1000000Ω, measure resistance value of metal materials, contact resistance of electrical equipment such as switches and relays, and DC resistance of motor and transformer windings.
