Best Uni T Electrical Testers in 2026

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. 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 / 48-1000V 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.

Customer Service: KAIWEETS provides a lifetime after sale service and technical support. This digital multimeter is included with 2 AAA batteries (pre-installed), comes with a carrying case and 2 decent cable leads.

Multi-Function: This multimeter can test AC/DC Voltage, DC current (Can not for AC current), Resistance, Continuity, Diode Measurement.

Sensitive Test: Please make sure the rotary switch is located at the right test range. Data hold function, backlight function helps you test clearly and quickly in a dim place.

Smart Mode: The multi meter defaults to Smart Mode. In Smart Mode, the meter can test voltage, resistance, and continuity automatically -- it can identify the measurement content and selects the range with the best resolution, you don’t need to do anything extra!

Upgraded Display: The voltmeter with a large LCD color screen, and flashlight for easy reading even in bright or dim places. In addition, the voltmeter can display analog bar, real-time temperature, low battery prompt, and damaged fuse prompt.

Wide Applications:This digital multimeter is suitable for diagnosing automotive, industrial and household electrical problems. The KM601 multimeter can accurately measure AC/DC voltage, resistance, continuity, AC/DC current, capacitance, frequency, diodes, duty cycle, temperature, NCV and live wire.

【Multi-function 】The circuit tester offers full range of electric measurements:AC&DC Voltage/Resistance/Continuity/Frequency/Capacitance//Live Wire/Diode/Phase Sequence.

【Non Contact Voltage Tester】The electric detector enables you to detect voltage without any contact which largely avoids electrical shock.

【Beeper&Indicator Bar】Both are activated when voltage is detected.The frequency of warning tone and the color of indicator light varies depending on the voltage level

【Multi Measurement】Enter the Smart (Auto) mode by default, the small multimeter pen automatically identifies and measures AC/DC Voltage, Resistance, and Continuity. It also tests Capacitance, Diode, Frequency, and Live Wire.

【Phase Sequence 】ST120 stands out with its unique phase sequence detection. When turn on the “PA” mode, the operator can detect whether the phase sequence is clockwise or anti-clockwise.

【Easy to Use】Switch measurement mode with button “Func” and hold data with button “H” . Backlight LCD screen ensures reading to be clearly seen in either dark or bright areas. The flashlight below the red probe helps you to work without concerns under dim light.

【More Safety】CE CAT.II300V RoHS Certificate. No gloves are recommended during the test, Testing AC voltage needs the human body and ground wire to form a circuit. No Electric Shock Risk, No Dangerous, More Accurate Readings. The current flowing through the human body is less than 0.1uA. (Min current the human body sense：1mA). The internal circuit of the Voltage Pen is connected in series with a large resistor, which will burn out when the current is too large, and the circuit will disconnect.

【Alarm Mode】The buzzer and indicator light will be triggered when voltage is detected. High-frequency beeps means high voltage and live wire are detected. Low-frequency beeps sound mean low voltage and null wire are detected.

【Measurable Voltage】Equipped with a sturdy metal NCV probe for testing AC voltage; the test probe touches the conductor with AC voltage, and the voltage reading will show on display. To obtain more accurate values, it is recommended not to wear gloves when using.

APPLICABLE MODELS:Tool case for Fluke117/115/116/114/113 Digital Multimeter, 101/106/107/F15B+F17B+F18B Pocket Digital Electrical Test Meter and KAIWEETS HT206D and More(Only case)

PREFERRED MATERIALSL: The shell is made of hard EVA environmental protection material, which has the functions of anti-drop, anti-tear, shockproof and dustproof, etc. The interior is lined with soft velvet cloth to protect your meter from scratches and damages.

INTERIOR DESIGN: In order to facilitate your carrying, we specially designed a wider handle belt, and the use of the YKK brand double zipper head, can be smoothly pulled 360 degrees slide, at any time to extract carry.

【Safe and Efficient】 Multimeter test leads are made of high quality, soft, high grade silicone insulation for flexibility and durability. Silicone helps to extend the service life and can be used in extreme environments. Strong electrical conductivity, low resistance, no signal loss. Lead wire: Cat III 1000V,10A.

【Variable combinations】 The head of the multimeter pen is a combination of banana plug and probe. It can be connected to any other accessories with 4mm socket in this kit. The combination is flexible and easy to use.

【Practicality】 Various combinations of piercing probes can meet your needs in different testing scenarios. Interchangeable multimeter test probes, alligator clips, test hooks and back probes can be used in different measurement environments, such as industrial, electronic, home and automotive.
