One of the most important parameters characterizing the quality of carbon products (graphite electrodes for electric furnaces, carbon blocks for electrolyzers, etc.) is electrical resistivity. The electrical resistivity value should be controlled both at intermediate technological operations and at the end of the production cycle to determine the brand of the product.
The IUS-4 meter is designed for the operational determination of the electrical resistivity of carbon-graphite products, including graphite electrodes and workpieces by one operator. The device allows measurements with end current input. The device is intended for use at enterprises of the electrode industry, as well as non-ferrous and ferrous metallurgy.
To determine the electrical resistivity of the nipples, the IUS-4 meter can optionally be equipped with two pairs of sensors, which are connected to the device probes with flexible wires.
To measure the electrical resistivity of graphite electrodes, a stationary version of the IUS-4s can be used as part of the measuring stand. In stationary version of the device is used higher measuring current, due to which a higher measurement accuracy is achieved. This device is equipped with an RS-232 interface for communication with a computer. Power supply of IUS-4s from a 220 V, 50 Hz network.
