The RST Helix from R.S. Technical Services is an advanced manhole inspection system designed to accurately identify sources of I&I, as well as structural deficiencies in sewer and stormwater manholes. The fully automated system can be economically deployed by a single operator from a van, pickup, ATV or CCTV vehicle, and will scan a typical 10-foot manhole in under a minute. It has six high-resolution cameras that capture panoramic imagery of every surface of a manhole, as well as six active 3-D sensors that record millions of data points for precise measurements. 800/767-1974; www.rstechserv.com; Booth 3610.
