Product introduction: The BSIDE X1 product is a future-oriented electrical tester created by the BSIDE brand designer. The product has a 2.0-inch smart display, and has the test attributes of a voltage detector and a smart multimeter. With the increasing importance of electricity safety, this product will become a neceity in your daily life. At the same time optimize the use of functions and test experience.And added the latest design of "High sensitivity detection mode"( 6V~1000V ). X2 products increase the function of Non-contact infrared thermometeron the basis of X1. The latest design in 2021 - Exquisite and unique. With a patent certificate, you can order with confidence. [EBTN LCD Display]: BSIDE EBTN LCD display greatly enhance the reading experience, the lighted up numbers & letters with black background make it very easy to read, even in bright sunlight or poor light. [8 LED Indicators]: 8 LED Indicators in 3 color make it very easy to judge the detected voltage strength. [3mm ultra-narrow frame design]: Leave more space for the screen. [3-Line Display]: High resolution large screen triple line display can show 3 test results on the screen, the voltage, frequency and analog bar. [Sensitivity Adjustable]: Adjustable sensitivity makes measurement more convenient, when adjusting to low sensitivity, it can more accurately distinguish the specific situation in complex lines.(High: 6V~1000V; Low: 90V~1000V) Sound and light/screen warning. Automatic shut-down. Low battery reminder. Sophisticated workmanship will bring you the best experience. BSIDE X1 products use the latest smart chip ( 16-bit chip ), which can intelligently identify all test functions. [Perfect test speed]: Real-time display of test results( 1s/5 tests ), bringing you unexpected fluency.
