RD500-Tx Transmitter

RD500-Tx Transmitter is an electronic pulse transmitter that provides a fast and reliable method to apply a traceable signal to plastic pipes carrying domestic water supplies. This pulsed signal can be located and traced by using a ground microphone to identify the location and path of plastic pipes.

RD500-Tx Transmitter consists of an electronic pulse transmitter, a supply kit containing the necessary connectors, hoses and power supply. The RD500-Tx differs from a conventional mechanical Pulse Transmitter by providing the required tracing pulse electronically and once connected it requires no manual adjustment of the water pressure to provide a traceable signal.

Part no: 10/RD500-TX
