Specifications: Display: LCD Frequency: 50/60Hz Alarm Mode: Sound and light alarm Probe Shape: Oblate shape Waterproof Grade: IP66 Product Size: 156x30x24mm/6.14 * 1.18 * 0.94 Description SAFETY FIRST: Our Dual-Range Non-contact Voltage Tester Pen prioritizes your safety by emitting multiple alarms through sound and light. When detecting voltage, the tip glows red and beeps, with higher frequencies indicating higher sensed voltage levels. The integrated LCD display shows percentage values, making it easy to identify high voltage (red) versus low voltage (green), ensuring reliable use as an electrical outlet tester NON-CONTACT TECHNOLOGY: This advanced voltage tester utilizes NCV inductive probe technology for AC voltage detection. Simply place the tip near a terminal strip, outlet, or supply cord. If the tip glows red and the pen emits a beep, you can confidently conclude that there is live electricity present. Its the ideal tool for electricians and homeowners looking for a reliable outlet tester plug in DUAL RANGE DETECTION: The voltage tester detects both standard and low voltage (12-1000V / 70-1000V , providing sensitive and flexible measurements. A simple press of the S button adjusts sensitivity levels, adapting to various applications, such as doorbells and thermostats. The built-in NCV sensor automatically identifies voltage levels, displaying the intensity on the bar graph for quick assessments HIGH SECURITY LEVEL: Rated IEC CAT III 1000V and CAT IV 600V, our electric tester complies with CE standards and features double insulation for maximum safety. The high voltage alert activates when voltage exceeds 90V, turning the screen red and illuminating the safety symbol, safeguarding you during electrical tasks COMPACT DESIGN FOR CONVENIENCE: Equipped with a bright LED flashlight for visibility in dim areas, this electric tester pen also has a low-power indicator and an automatic power-off feature after 5 minutes of inactivity. Its pocket-sized design and convenient pen hook make it easy to carry Product Includes: 1set * Dual-Range Non‑contact Voltage Tester Peninch
