The Parrotias tester accurately detects a standard and low voltage (12-1000V AC / 48-1000V AC), which is more sensitive and flexible. Low sensitivity can probe power supply lines such as power boards, desk lamps, computers, etc. and high sensitivity can detect buried walls and other internal wiring detection (depth≤1.18 inches).
