The 8873 cable, pipe, camera and sonde locator from RYCOM Instruments offers two versions of the dual active frequency packages — 512 Hz and 82 kHz or 512 Hz and 33 kHz — ensuring the ability to track any manufacturer’s camera or sonde system operating on 512 Hz. It can be used to locate pinches and blocks in nonpressurized conduits and pipes, as sonde frequencies are matched to the frequency of the receiver. Sondes at all frequencies will trace through conduit up to 20 feet in the air or 10 feet in cast iron. The receiver pinpoints inspection cameras and sondes in nonmetallic conduits in a peak mode. A backlit digital display provides both relative and actual signal strength. A variable tone pitch gives an audio indication to the signal. The triple antennae configuration provides push-button depth accurate up to 15 feet and works in peak, pinpoint peak and null modes when used with a transmitter. 800/851-7347; www.rycominstruments.com.
