TDL 220 Tunable Diode Laser

TDL 220 Tunable Diode Laser

  • ICI’s TDL 220 (Tunable Diode Laser) is an advanced handheld system which detects methane gas (CH4) at distances of up to 20 m (65.6 ft) at volumes of 0 ppm.m to 100,000 ppm.m.
  • Traditional methane detection methods are costly, time consuming, places valued personnel in harms way, and impacts a company’s bottom line.
  • Adding the TDL 220 detector to predictive maintenance plans helps users quickly and safely identify methane gas leaks.
  • It is ideal for inspections of distribution pipelines, petrochemical industrial refineries, chemical plants, metallurgical production lines, or other potential hazardous locations.
