MUSTOOL MT109 Portable 9999 Counts True RMS Multimeter AC DC Voltage Current NCV Temperature Tester Auto Range Backlight and Flashlight With Black EBTN Screen

The second product launched by MUSTOOL team in this summer. Upgraded to more powerful than MT108 HD black EBTN screen. Integration design inside and out. 9999 counts high precision measurement. Features: The 9999counts is a pocket-sized 3 9/10-bit automatic digital instrument. It has the features of stable performance, high precision, high reliability ,clear readings, and overload protection . With AAA 1.5V battery-driven,the instrument uses a large-screen LCD display,boost power supply, even in the 2.3V low battery edge, it can guarantee the backlight high brightness, It is easy to carry, is a vast number of users extremely like the instrument. This series of instruments can be used to measure the DC voltage and AC voltage DC current and AC current, resistance, capacitance diode,continuity test, frequency measurement and true RMS measurement and other parameters. It is an ideal tool for the laboratory, factory, radio enthusiasts and families. 1. True RMS 2. NCV 3. Auto range 4. 9999 Counts display 5.
