Saftest electrical tester : CEM’s explosion-proof voltage tester protects electrical safety
The voltage tester is one of the essential electrical safety tools for households, playing a vital role in daily tasks such as checking socket live status and inspecting potential wiring hazards during renovations.
CEM's AC-15EX/15EXS explosion-proof NCV non-contact voltage testers, with their "zero-contact voltage measurement + explosion-proof and waterproof" design, have become safety assistants for both household and industrial users.
Industrial-grade safety protection, adaptable to multiple scenarios
In electrical maintenance and renovation work, safety is always the top priority. The CEM AC-15EX/15EXS explosion-proof NCV non-contact voltage tester is a professional tool designed specifically for high-risk environments. It uses inductive measurement technology, allowing voltage detection without direct contact with the power source.
As a device with outstanding safety performance, the AC-15EX/15EXS complies with the CAT IV 1000V safety standard and employs non-contact voltage measurement technology, effectively ensuring the safety of operators.
This product has passed the II2G Exib op is II B T4 Gb explosion-proof certification, meeting the operational needs of flammable and explosive environments such as coal mines and petrochemical industries. Its dual-injection molding shell design, combined with an IP67 rating for waterproof and dustproof protection, ensures stable performance in humid and dusty environments. The ultra-thin probe design also makes it easy to access narrow spaces, such as wall sockets.
Electrical testing: "Visible and clear sound"
The AC-15EX/15EXS features red, yellow, and green LED indicators along with a buzzer alarm system, offering dual-range modes for full coverage of both strong and weak electrical scenarios.
High voltage mode (green indicator light): Detects AC 100~1000V voltage, suitable for strong electrical systems such as 220V mains electricity and 380V three-phase power.
Low voltage mode (yellow indicator light): Detects AC 12~1000V voltage, supporting detection of low-voltage devices such as AC 24V/48V/60V systems. When AC voltage within the range is detected, the yellow light goes off and the red light flashes. The faster the detected AC voltage, the faster the red light flashes.
The voltage range is adjustable between high and low. When the detected AC voltage reaches the high voltage range, the device will automatically switch to high voltage mode. Alternatively, the range can be switched manually by holding down the "12V" button. The alarm frequency changes in real time according to the voltage strength. The AC-15EXS also features a vibration reminder function, creating a "visual + auditory + tactile" triple warning system.
The user-friendly design is reflected in the product's details, with a pen clip structure for portability. The dual-direction flashlight system (fine detail illumination at the pen tip and strong spotlight at the pen cover) enhances the convenience of detection. A 5-minute automatic shutdown mechanism extends battery life, and the silent mode meets the needs of special environments such as libraries and hospitals.
Four Core Application Scenarios of Voltage Testers
From daily circuit repairs to industrial equipment maintenance, the AC-15EX/15EXS non-contact voltage tester combines safety protection with practical functionality, providing reliable technical support for electrical testing.
- Invisible Breakpoint Localization
Move along the line to detect the status of the circuit. Breakpoints are identified through sound and light changes:
Powered segment: Red light + continuous beeping
Breakpoint location: Green light + beep stops
This function is especially useful for detecting issues such as aging wiring in old houses or faults in hidden wires after renovation.
2. Neutral and Live Wire Identification
When installing lamps or sockets, you can accurately distinguish between the neutral and live wires without relying on experience, avoiding short circuits or electric shock risks.
Live wire detection: Red light on + high-frequency beep (the higher the voltage, the higher the frequency)
Neutral wire identification: Green light on/low-frequency flashing + weak beep
3. Hidden Wiring Detection in Walls
After renovations, the voltage tester can be used to scan hidden wires behind walls and under floors. If a non-energized area lights up with a red light, it indicates a leakage or wiring error. With the silent mode, you can perform night-time inspections without disturbing family members.
4. Home Appliance Maintenance
Check for leakage in high-power appliances such as refrigerators and washing machines.
Electrical safety is no small matter. A professional voltage tester is not just a tool, but a guardian of the safety of both your family and yourself. The CEM AC-15EX/15EXS, with military-grade protection, intelligent early warning, and user-friendly design, redefines the definition of a safety tool.
