The YBL-III zinc oxide surge arresters live Tester
Product Description
This product is a special test equipment for field and laboratory testing arrester relevant electrical parameters. This instrument is advanced microcomputer control and computing core, using precise mathematical model, and give full consideration to the external instruments to measure the interference, accurate and reliable measurement of the software itself. Instrument the special weak signal sensors, the instrument measured arrester isolation, to ensure the safe use of the user and the instrument. Large-screen LCD display, Chinese menu operation makes the machine switched more powerful, while providing on-site wiring and and backlit instrument provides features that make it in the outdoor display remains clear and easy to use.
