YT-28320 Non-contact voltage tester 12-1000 V

Works on the principle of electromagnetic induction - the closer to the voltage source, the higher the reading frequency
Allows non-contact detection of a break in a live electrical wire - at the break the tester stops signalling the presence of voltage

AC voltage detection by the inductive method: 12 – 1000 V
Low-sensitivity mode - at a distance of up to 1 cm from an insulated wire, intense readings after touching the wire
High-sensitivity mode - up to 5 cm from an insulated wire, intense readings up to 1 cm from the wire
Wire continuity check by the inductive method
Workplace illumination by a built-in white LED
Probe length 165 mm
Has audible and visual indication (LED), as well as an LCD display
Automatic tester shut-off after 3 minutes
Low battery indication
Power source 2x AAA
