🔧 CEM AC-15EXS & AC-6 – Non-Contact Voltage Tester Combo (Use Together) Why two testers? No single tool fits every job. CEM pairs two professional voltage testers so you can choose based on voltage range, work environment, and safety requirements. 👷 For Industrial Electricians & Field Technicians Work environments: Outdoor panels, wet ditches, dusty workshops, chemical plants, explosive atmospheres Primary tool: AC-15EXS ATEX certified (IIB T4 Gb) for potentially explosive areas IP67 rated – dust tight and protected against temporary immersion CAT IV 1000V – suited for service entrance and utility connections Vibration + beeper + red LED – no missed alerts near loud equipment Built-in flashlight + worklight – illuminate dark electrical cabinets Low voltage mode (12V–1000V) – test doorbells, thermostats, USB cables (AC ripple) 🏠 For Homeowners, Landlords & Property Maintenance Daily needs: Check outlets, light switches, extension cords, breakers Primary tool: AC-6 Detection range: 50V–1000V AC – covers standard household voltages One-button on/off, beeper + green/red LED Pocket clip for easy carry Affordable backup or quick-scan tool alongside AC-15EXS 🔄 How to use both testers together Well-lit & ≥50V – Start with AC-6 for a fast scan Below 50V or dark/wet/dusty – Switch to AC-15EXS with 12V mode + flashlight High-risk jobs (outdoor, damp, confined) – Must use AC-15EXS Before trusting a “dead” circuit – Cross-check with both testers ⚠️ Safety & compliance notes (for both models) Test on a known live AC source before and after each use to verify operation Insulation thickness, shielded wires, or distance from source may affect detection. If uncertain, verify with a contact voltage tester Low battery: green LED off or 3 beeps/vibrations → replace two AAA batteries immediately AC-15EXS: screw-on battery cap – tighten firmly to maintain IP67 seal AC-6: locking tab cap – slide until click This device does not detect DC voltage.
