Providing safe and practical high-voltage alarm devices for real-time operators to ensure their safety. The high voltage alarm has ultra-high sensitivity, which can detect voltage as low as 40V. Using non-contact sensing technology, it delivers accurate alarms, is energy-saving, durable, and features a standby time of up to 12 months. Features direction induction voltage detection with automatic trigger mode and audible/visual alarm alerts to enhance worker safety near electrical sources. The high voltage detector is lightweight, reducing operator burden and improving ease of use.Item Type: High Voltage Alarm Material: ABS Model: ETCR1860 Voltage Detection Range: 40V 1kV Alarm Distance: 5cm to 60cm depending on voltage level Technical Parameters: Working Power Supply: 1 x CR1632 button battery (not included) Detection Range: 40V 1kV (ETCR1860C model) Distance Error: 10cm (under standard conditions: 231, 80%RH) Working Frequency: 50/60Hz Electric Test Mode: Non-contact Detection Mode: Automatic trigger Battery Life: Continuous alarm operation: approximately 24 hours Standby Time: Up to 12 months Alarm Mode: - Indicator Light: LED visible under 8000LX ambient light - Buzzer: >60dB at 60cm distance Protection Grade: IP54 Operating Environment: -10 to 40;
