Advanced Visual Voltage Inspection: MESTEK AC50 / AC50A Dual-Range LCD Non-Contact AC Voltage Detector Series in Malaysia

For professional electricians, safety inspectors, HVAC technicians, and industrial plant engineers across Malaysia, rapid and unambiguous voltage identification is critical to maintaining safe working conditions. MTM Precision is proud to present the MESTEK AC50 and AC50A Dual-Range Non-Contact AC Voltage Detector Series—advanced voltage testing pens equipped with clear LCD screens, dual-sensitivity switching, and comprehensive visual/audible alarms.

Rated for CAT III 1000V / CAT IV 600V safety compliance with official CE and RoHS certifications, the MESTEK AC50/AC50A series provides exceptional visual feedback via LCD screens (Black & White on AC50 vs Colorful LCD on AC50A), intelligent live/neutral line discrimination, dual-range sensing (12V–1000V / 48V–1000V), an integrated LED flashlight, and a ruggedized housing capable of withstanding 2-meter drop tests.

🌟 Key Features & Advanced LCD Visual Capabilities

Dual-Range AC Voltage Detection (12V~1000V / 48V~1000V): Easily switch between standard mains range (48V–1000V AC) for general electrical panels and high-sensitivity range (12V–1000V AC) for low-voltage control circuits, thermostats, and signaling lines.
High-Clarity LCD Screen Display:
- AC50: Features a sharp Black & White LCD screen displaying analog signal bars, frequency, and live status.
- AC50A: Upgrades to a vibrant Colorful LCD Display that delivers dynamic, color-coded visual intensity bars for instant voltage magnitude recognition.
Intelligent Live & Neutral Line Discrimination: Automatically distinguishes live conductors from neutral wires based on detected signal strength, analog bargraph levels, indicator lights, and variable audio frequencies.
Comprehensive Tri-Mode Alarm System: Combines digital screen graphing, audible buzzer beeps, and flashing light alerts to provide clear confirmation of voltage presence.
Rugged 2-Meter Drop Test Durability: Engineered with a heavy-duty, impact-resistant ABS polymer casing designed to survive demanding industrial job sites and accidental drops up to 2 meters.
Integrated LED Flashlight: Built-in white LED work light illuminates unlit breaker boxes, ceiling spaces, and subterranean electrical vaults.
Auto Power Off & Low Battery Protection: Automatically shuts down after 5 minutes of inactivity to preserve battery longevity.
