JUNTEK DC 0.01-100V 0.01-30A Multifunctional Wireless Digital Bi-directional Voltage Current Power Meter Ammeter Voltmeter Capacity Coulomb Counter

Features: The display module shell adopts sandblasting oxidation technology, beautiful and elegant. Touch control buttons with high sensitivity and long service life. The measuring module needs to be connected in series to the circuit under test, and send the measured data to the display module for display. The data between them can be transmitted via USB cable (1 meter long), it can also be wirelessly transmitted through the built-in wireless module. The wireless transmission distance is up to 10 meters. The measuring module can detect the current in both directions. No need to change the wiring mode during the charging and and discharging of the battery, and it's convenient for wiring. Adding self-calibration function to solve the problem of zero drift in old products. After a long time of work, the current and capacity can still maintain a great accuracy. With 3 display modes. The default display is the large font mode, displaying the main parameters of voltage, current, ca Discounted at only: US$ 41.95
