GEST-125 Semi-conductive rubber and plastic material volume resistivity tester
product description: The semi-conductive rubber-plastic resistance tester is a precision measuring device successfully researched according to the national standard GB3048.3. It is mainly used to measure the resistivity of the intermediate samples of rubber and plastic semi-conductive materials for cables and the resistance of various conductive rubber-plastic products. It can also be used Four-terminal test clips measure the low and medium resistance of metal conductor materials and products. The instrument consists of two parts: the main engine and the test frame. The host includes a highly sensitive DC digital voltmeter and a highly stable DC constant current source. The measurement results are directly displayed by LED numbers, which are divided into 3 windows: voltage display window, material thickness display window (user input according to actual measurement), resistivity display window. The instrument has the characteristics of high measurement accuracy, good stability, compact structure and convenient use, and fully meets the requirements of international and national standards. The instrument is suitable for cable factories, conductive rubber and plastic material factories, computer factories, electronic watch factories, colleges and universities, scientific research and other departments. It is a necessary test equipment for resistance performance testing and process testing of conductive rubber and plastic materials and products. Features: 1. The technical performance fully meets the requirements of the national standard GB3048.3, with standard size current electrodes, voltage electrodes, and pressure systems, and the insulation strength of the sample box is greater than 1012Ω. 2. Advanced technology, reliable work, large working temperature range, made of high-strength, high-insulation and temperature-resistant materials, and placed in an oven, it can work continuously for a long time from 0 to 180 °C. The change of resistivity under high temperature conditions provides a strong guarantee. 3. Simple operation, easy to use and long life.
