Are you looking for a non-contact method to detect the presence of AC voltage in wires, outlets, switches, circuit breakers, and other electrical devices? If so, a non-contact voltage tester might be the ideal solution for you. These testers allow you to measure AC voltage without touching the electrical circuit, reducing the risk of electric shock and injury.
What Is a Non-Contact Voltage Tester?
A non-contact voltage tester is a handheld tool designed to detect AC voltage without physically touching the circuit. It’s an essential tool for electricians and DIY enthusiasts, commonly used to:
- Inspect the wiring in a new home
- Troubleshoot faulty appliances
- Confirm the power supply to devices
Comparing Two Popular Non-Contact Voltage Testers
Non-contact voltage testers are available in various sizes, designs, and with different functionalities. In this article, we’ll compare two popular models: the Chauvin Arnoux C.A 732 Non-Contact Voltage Tester and the Tekneka TK10 AC Voltage Detector. We’ll explore their features, advantages, and drawbacks to help you determine which one suits your needs best.
Tekneka TK10 AC Voltage Detector: Features and Benefits
The Tekneka TK10 AC Voltage Detector is a pen-shaped device that detects AC voltage between 12 and 1000 VAC without making any direct contact with metal. This tester offers:
- Wide Voltage Detection Range: It can detect both low and high voltages, making it versatile for different applications.
- Visual and Audible Indicators: When voltage is present, a red LED flashes, and an audio alert sounds, making it easy to notice even in noisy environments.
- Built-In White LED Light: This is useful for working in dimly lit areas.
- Low Battery Indicator: It alerts the user with a beep and a green LED flashing three times before the device shuts off.
- Portability: Weighing only 35 grams and measuring 156 x 23 x 26 mm, its pen-like size and clip make it easy to carry in your pocket.
The Tekneka TK10 is powered by two 1.5V AAA batteries (not included), providing up to 200 hours of continuous use. With a CAT III 1000 V safety rating, it offers sufficient protection for most electrical testing tasks.
Advantages of the Tekneka TK10:
- Detects a wide range of voltages (12-1000 VAC)
- Visual and audible alerts for easy identification
- Integrated white LED light for visibility in low-light conditions
- Lightweight and easy to carry
Drawbacks of the Tekneka TK10:
- Runs on batteries, requiring periodic replacement
- Lacks a phase identification feature to determine live vs. neutral wires
- No built-in torch function for enhanced lighting
Chauvin Arnoux C.A 732 Non-Contact Voltage Tester: Features and Benefits
The Chauvin Arnoux C.A 732 Non-Contact Voltage Tester is another pen-shaped tool designed to detect AC voltage between 195 and 265 VAC. Here are its key features:
- Phase Identification: This feature illuminates the tip of the tester when it detects voltage (230 V AC – 50/60 Hz), allowing you to identify whether a wire is live or neutral.
- Built-In Torch: The integrated torch is useful for working in low-light areas, serving as both a voltage detector and a flashlight.
- Multilayer Insulation: Provides extra protection against electric shock and damage.
- Durable Design: It measures 35 x 145 x 285 mm and weighs 135 grams, with a CAT III 1000 V safety rating.
Advantages of the Chauvin Arnoux C.A 732:
- Built-in torch for use as a flashlight in low-light conditions
- Phase identification feature to distinguish between live and neutral wires
- Multilayer insulation for added safety
Drawbacks of the Chauvin Arnoux C.A 732:
- Limited voltage detection range (195-265 VAC)
- No audible alert or red LED for easy voltage identification
- Lacks a low battery indicator
- Larger and heavier than the Tekneka TK10

| Low Battery Indicator | Yes | No |
| Weight | 35 g | 135 g |
| Dimensions | 156 x 23 x 26 mm | 35 x 145 x 285 mm |
| Safety Rating | CAT III 1000 V | CAT III 1000 V |
Which Non-Contact Voltage Tester Should You Choose?
Both the Tekneka TK10 and Chauvin Arnoux C.A 732 have distinct features that cater to different needs.
- Choose the Tekneka TK10 if you need a lightweight, portable device with a wider voltage detection range (12 – 1000 VAC) and visual and audible indicators.
- Opt for the Chauvin Arnoux C.A 732 if you prefer a tester with a built-in torch and phase identification to distinguish between live and neutral wires, despite its narrower detection range and heavier build.
Regardless of your choice, always follow safety guidelines and instructions when using voltage testers. Make sure to test the device on a known live circuit before using it on an unknown source. Happy testing!
