1、 Product Introduction:

GB-2439Type conductivity andSemi conductive rubberMaterial volume resistivity testerThe complete testing system is composed of four probe instruments and uses the parallel four knife method Professional measurement of electrical resistivity of semiconducting rubber materials or films based on the principle of four terminal measurement/Multi purpose comprehensive measuring device for square resistance Complies with the national standard for the rubber and plastic industry, GBT 3048.3-94 Test Methods for Electrical Properties of Wires and Cables - Volume Resistance Test of Semiconducting Rubber and Plastic Materials

GB/T 2439-2001 Determination of Electrical Conductivity and Dissipation Properties of Vulcanized Rubber or Thermoplastic Rubber.The electrode group lifting and lowering of this test bench is a fast constant voltage manual mode, which has the characteristics of good stability, compact structure, and easy measurement. sample The box is made of materials that are resistant to high temperatures, corrosion, and high insulation, and is equipped with connecting electrodes. This makes it easy for clean standard samples to be clamped Drying, aging, testing, moving, etc., while avoiding contamination caused by hand contact with the sample and affecting testing accuracy. The instrument is suitable for semiconductor thin film material factories, rubber and plastic material factories, metal thin film material factories, capacitor factories, scientific research institutions, higher education institutions, etc Testing of square resistance and electrical resistivity properties of semiconductor or rubber materials.
