SAFE&PRACTICAL:Non-contact AC voltage detector Just place the tip near a terminal strip, outlet, or supply cord.When the tip glows red and the pen beeps, you know there's voltage present.Professional factory design and production,safe and reliable.

SECURITY LEVEL:The electrical tester is safely insulated can detecting 60V-1000V AC voltage.Safety Compliance:CAT.IV.ETL.CE.In order to use safely,it is recommended that you do not insert the pen head directly into the power supply,and wear gloves.

MULTI-FUNCTION:It has the flashlight can help you work much better in dark.When it detects AC voltage, detection light will flash red and buzzer will sound short beeps.

VERSATILE DIGITAL MULTIMETER: Suitable for all kinds of household use and industrial use. Can be use at Household Outlets, Fuses, Batteries (including Vehicles), Automotive Circuit Troubleshooting, Charging System, Testing electronics in Cars etc. It is a AC/DC Voltmeter, Ohm Volt Amp Tester, Electric Ohmmeter, Diode, Resistance and Audible Continuity Detector.

Troubleshooting with Speed and accuracy: This Multimeter has a sampling speed of 2 times per second; Built-in a backlight LCD display with 3 ½ digits (1999 count) 0.6”, and high polarity including negative and positive readings.

Electronic Tester Multimeter with Over-load Protection and Low-Power Reminder: Use the PTC protection circuit for Resistance, and frequency measurement. Over-load indication "1" will be displayed; Low battery indication will be displayed when battery power is low.

Non-Contact: ADWSET voltage tester with NCV sensor probe for AC voltage; simply place the tip near a terminal strip, socket or power cord. You will know voltage presents when the tip glows YELLOW and the pen beeps. The live wire detector can automatically detect the live wire and the neutral wire. Ideal for breakpoints testing.

Quick Response and Guaranteed Safety: Multiple alarms through sound and light. When low voltage is detected, the tip will flash yellow light and the buzzer alarm will sound loudly. When the detected voltage is higher, or the voltage source is closer, it will beep at a higher frequency and the tip will glows RED. Red means high voltage and live wire is detected, yellow means low voltage and neutral wire is detected. A convenient circuit tester for electricians and homeowners.

Adjustable Sensitivity and Dual Range Testing: Adjustable sensitivity makes the measurement more sensitive and flexible; the non contact voltage tester has dual test ranges (H: 12-1000V AC/ L: 48-1000V AC), in the state of high sensitivity, even 11V Low voltage can also be detected.
