Signal Group’s sample handling modules and components condition gas samples in preparation for analysis. 1/8”, ¼”, 3/8” and ½” versions, and their metric equivalents (3mm, 6mm, 10mm, 13mm). 1m to 50m in length. Signal Group’s Trace heated line is designed to convey hot exhaust gasses from sample points and probes to analyser, without compromising sample integrity. With safety a major consideration the tough, flexible line is electrically isolated from the main supply and is thermally insulated to allow handling even at full temperature.
