Capacitance Tester: measuring high voltage and high power, summarizes a variety of large-scale instruments and uses precision devices to develop, voltage up to 32V, power up to 160W, from other industrial high voltage power supplies and fast charge voltage range measurement. Clear data display: high brightness, large field of view, low power consumption, full visual readout and durability, whatever either angle, you can clearly see the colorful and beautiful content of the data. USB 3.0 Data Transmission: USB 3.0 data transfer is faster, supports current measurement, and has wider application. USB peripherals are widely compatible with 3C digital peripheral products, such as: USB charger, mobile power supply, electronic charging, USB light and 3.0U disk, etc. USB 3.0 color screen security detector - Charging uses "USB 3.0 color screen security detector" to safely charge the mobile phone, over voltage, over current, low voltage protection, low power consumption alarm, built-in buzzer is easy and safe to be measured. Data guaranteed --- With the function of automatically saving data after power off, the data is guaranteed. When the power is on, the data from the last test will continue to be accumulated to prevent data loss during the test. Features: Condition: new. Item type: USB detector. Material: plastic.
