Digital multimeter ac / dc voltmeter battery tester ap
This digital multimeter (8221D) is a portable measurement instrument with 3 LCD display. 8221D can perform testing on AC / DC Current and Voltage, Resistance, Battery (1.5 V / 9 V), Diode and Continuity Check.
Besides of it great functionality, 8221D also has Data Hold function, Overload protection, low battery indication and double insulation for safety. This multimeter is an ideal instrument in schools, laboratories, industries and home applications.
