NEW Non-Contact Voltage Detector Pen 10S & 11S Smart, Safe, and Sensitive from 24V to 1000V AC

1. Dual-Model Flexibility for Every Voltage Scenario
The non-contact voltage detector series includes the 10S and 11S, covering a wide AC voltage spectrum. The 10S reliably detects from 90V to 1000V, perfect for standard household and industrial circuits. The 11S goes further, detecting as low as 24V AC—ideal for low-voltage systems, control circuits, and sensitive electronics. Whether you’re troubleshooting a 24V HVAC system or a 1000V industrial panel, you never need to touch bare wires. This non-contact functionality dramatically reduces electric shock risk and speeds up diagnosis.

2. Enhanced Sensitivity with Adjustable Ranges
Both models offer adjustable sensitivity, but the 11S adds distinct high and low sensitivity ranges. In high-sensitivity mode, it detects 24V–1000V AC, allowing you to trace live wires through insulation or locate breaks from a distance. In low-sensitivity mode (90V–1000V AC), it helps pinpoint exact wire locations and reduces false triggers in crowded junction boxes. This makes the 11S an advanced non-contact voltage detector for professionals who need precision and control. The 10S still provides excellent adjustable sensitivity for standard tasks.

3. Zero Fire Line Distinction – Smart Polarity Indication
Both pens feature zero fire line distinction, a critical function for identifying live (fire) vs. neutral wires without contact. Simply move the tip near a socket or switch; the detector differentiates between lines using intelligent induction. This is invaluable for correct wiring during installations, renovations, or fault-finding. Combined with audible beeps and bright flashing lights, the detector gives clear, unmistakable feedback even in noisy or dark environments.

4. Built-In Flashlight and Low-Pressure Tips
Dark electrical panels and cramped crawl spaces are no problem. Each unit includes a flashlight to illuminate your workspace, leaving your other hand free. Additionally, low pressure tips (low battery indication) alert you before the battery dies, preventing unreliable readings. The automatic shut-down activates after about 5 minutes, preserving battery life and ensuring the detector is ready when you need it.

5. Rugged Environmental Tolerance
With an operating temperature range of 0–40°C and storage from -20–50°C, these non-contact voltage detectors perform reliably in shops, factories, outdoor sites, and maintenance rooms. The 50/60Hz frequency compatibility covers global power systems. Whether you’re working in a hot attic or a cold warehouse, the 10S and 11S maintain consistent accuracy.

6. Breakpoint Detection and Wire Tracing
The keyword here is non-contact voltage detector – and breakpoint detection is where it shines. Run the tip along a cable; the alert stops at the break point, saving hours of cutting and testing. For renovation or demolition, quickly identify which breaker controls a circuit. For appliance repair, check if power reaches a motor or light fixture without stripping wires. Both models support this seamless tracing, but the 11S’s extended low-voltage range adds extra capability for data centers, security systems, and low-power lighting.

7. Automatic Induction – No Buttons to Hold
The working mode is automatic induction, meaning the pen constantly senses voltage when powered on. There’s no need to press a button while testing—just bring the tip close. This hands-simple operation reduces fatigue during long troubleshooting sessions. The beep and flashing light work together, so you never miss an alert even in high-decibel environments.

8. Safety First – Non-Contact Is Non-Risk
By design, a non-contact voltage detector isolates you from live parts. The 10S and 11S use capacitive coupling to sense electric fields, so you never pierce or touch insulation. Safety is further enhanced by the zero fire line distinction and adjustable sensitivity that prevents misreads on ghost voltages. For professional electricians, maintenance staff, and serious DIYers, these tools meet daily demands for fast, touch-free voltage presence checks.

9. Compact, Portable, and Ready to Use
Both pens fit easily in a pocket or toolkit pouch. The flashlight doubles as a work light. The 5-minute auto shut-off ensures you won’t return to a dead battery. And the low-pressure tip removes guesswork about battery status. From residential socket testing to industrial motor control verification, the 10S and 11S are the reliable non-contact voltage detectors that combine simplicity, intelligence, and extended voltage coverage – including the unique 24V capability in the 11S.

Choose the 10S for 90V–1000V tasks, and the 11S when you need down to 24V AC with dual sensitivity ranges. Both deliver beep + flash alerts, zero fire line distinction, flashlight, and auto shut-off. Upgrade your electrical safety and efficiency today with these professional-grade non-contact voltage detectors.
