Product description

KAIWEETS Upgraded Version Non-Contact Voltage Tester

√ Larger LCD digital display screen

√ With voltage signal intensity percentage value

Adjustable sensitivity with dual range

High Sensitivity Mode: 12V – 1000V ACLow Sensitivity Mode: 70V – 1000V AC

Beeps at different frequencies

When the voltage is detected, the tip will send out red light and beep. When the higher the sensed voltage is, or the closer it is to the voltage source, it beeps at a higher frequency.

More intuitive percentage display

You can judge the detected voltage signal strength through the percentage value and bar graph.

Red LED flashing

If AC voltage is present at the measuring point, this is indicated visually by a red flashing LED. If there is no voltage at the measuring point, the screen will light up green continuously.

Saving Power

Automatic Power Off after 5 minutes without operation or signal detection

2 x 1.5V AAA batteries

Low Battery Indicator

If the battery voltage falls to less than 2.5 volts, the display shows a low battery symbol. When the battery voltage drops below 2.3 volts, the tester will automatically turn off.

LED Flashlight

You can press and hold the “S” button for more than 2 seconds to turn the LED flashlight on/off. The LED flashlight provides convenience in a dark environment.

SAFETY FIRST: It will send out multiple alarms through sound and light. When the voltage is detected, the tip will send out red light and beep. When the higher the sensed voltage is, or the closer it is to the voltage source, it beeps at a higher frequency and the percentage value will be larger. At the same time, the screen will be red or green, red means high voltage and live wire are detected, green means low voltage and null wire are detected
NON-CONTACT: With NCV inductive probe for AC voltage; 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. The live wire detector can automatically detect the live or neutral wire. Ideal for breakpoint Test. Handy circuit tester for electricians, homeowners
DUAL RANGE: Detects standard and low voltage (12-1000V AC / 70-1000V AC) for more sensitive and flexible measurements. Press the S button to adjust sensitivity and adapt low range for doorbells, thermostats, irrigation wiring etc.; The NCV sensor automatically recognizes the voltage and displays it on the bar graph, and the percentage value can display the voltage signal intensity more intuitively
SECURITY LEVEL: IEC rated CAT III 1000V CAT IV 600V, Meets CE requirements; The electrical tester is safely double insulated. High Voltage Alert to warn you of voltage above 90V, the screen turn red and the safety symbol on the screen shines
COMPACT DESIGN: Bright LED flashlight for work in dim ares; Low-Power-Indicator when battery voltage is below 2.5V; Automatic Power Off after 5 minutes without operation or signal detection; Pocket-sized, pen hook allows you to carry it in your shirt pocket. We provide 36-Month after sale service, Please feel free to contact us if you have any concerns
