Fieldpiece Non-Contact Voltage Sensor w/ LED & Buzzer

The SNCV1 non contact voltage tester senses live voltage without touching the object being tested so you know whether a wire is HOT or NOT. Features: Senses 24VAC to check power to the thermostat Also senses 120VAC and up so there's no need to carry two sensors Conveniently clips to a shirt pocket Differentiates between hot and neutral A bright LED and buzzer indicate A/C voltage sources Operates just like the non-contact voltage sensors of other Fieldpiece products Analog Feel: the closer the sensor is to the voltage source, the louder and brighter the indicators become Batteries included
