Test on the insulated material surface, apply a certain voltage between 2mm×5mm platinum electrodes for 30 seconds, then drip a conducting liquid (0.1% NH₄Cl) at a height of 35mm to test the tracking resistance of the solid insulated material under a humid environment and electric field. It can also test CTI and PTI. This instrument complies with the following international and industry standards. IEC: IEC 60112. Using a digital instrument control system and imported control components. The fixture is made of high-quality stainless steel, corrosion-resistant and rust-free. One-button timing device for convenient equipment use and simple operation. Advanced temperature control and temperature measurement system make the test more accurate and the results more reliable. Tempered glass observation window allows observation of the entire test process.
