Extech RT30: Wireless AC Circuit Identifier (914MHz) with External Probe
Local & Remote non-contact Voltage Detection + Remote Light Detection
The versatile RT30 uses a pager-sized, non-contact voltage detector transmitter which clamps onto wiring mid-run and transmits a "voltage present" signal to a pocket-sized receiver carried by the user. Clamped onto a live wire, the transmitter signals the user at the breaker panel with LED and audible alerts on the receiver (up to 100 m range). The alerts stop when the correct circuit breaker is switched and work can then be performed safely. You get the RT30 Wireless Remote AC Circuit Identifier with transmitter and receiver, remote clamp-style probe, 4 AAA batteries, pouch case, and operating instructions.
NOTE: USA, Mexico, and Canada use 914MHz model and majority of other countries use 869MHz model
