Digital ohmmeter DO 200/2000.P is designed to measure ohmic resistance in ignition networks in blasting operations. Measuring is automatically started once a measured resistance is connected. Due to its circuitry and construction it is intended to be used above ground, underground and also in environments with the risk of explosion. Part of delivery is also a casing from artificial leather which protects the input clamps from short-circuit.
