Additional safety device for individual use. Personal omnidirectional electric field detector. When the operator approaches an electric field between 10kV and 66kV and exceeds an approximate distance of 1m for 10 kV and 3m for 66kV, the detector emits a sound to inform the operator that he/she is in a danger area, and the sound will continue until the operator moves away from the voltage source.

• Optimized for use in distribution / transformer substations & overhead lines
• Operating range: 10 kV to 66 kV
• Operating frequency: 50 and 60Hz
• Powered by two LR-03 batteries
