The 3-in-1 tester is combined with the function of smart multimeter, voltage tester, and hidden wire detector, can measure DC voltage, AC voltage, resistance, frequency, continuity, V~Alert, and live wire in wall, and more, which is suitable for electrical device maintenance.

Features:
Practical Multimeter: has functions of measuring DC voltage, AC voltage, resistance, frequency, continuity, V~Alert, and live wire in wall.
Safety Operation: with CAT II 400V over-voltage standard, double insulation protection, and full measuring range overload protection.
Socket Live Wire Distinguish and Live Wire in Wall: once detected the live wire or the hidden wire under wall depth within 5cm, the buzzer will sounds up and the indicator lights up to remind you.
Other Features: built-in LED flashlight for auxiliary lighting, large HD LCD display for clear reading, 2 minutes auto-off for saving power, and has low battery indication to remind you replace the battery.
Compact Multimeter: compact portable size, easy to operate, the multimeter is suitable for handling the automotive and household electrical problems.
