This massive multimeter has everything but the kitchen sink included. It's a great addition to any workbench or toolbox.  It's low cost, simple to use, and has a big clear display with all the measurements you need and more!

The multimeter includes:

• AC/DC Voltage measurement
• Current measurement, from 2mA range up to 20A range (both AC and DC)
• Beeping continuity test, and diode test for measuring voltage and lighting up LEDs
• Resistance
• Capacitance
• Transistor hFE (Beta)
• Auto-power off, so the included battery doesn't get worn down

Comes with two probes as shown.
