Poissy, France 9/1/16—Environnement SA, a provider of online environmental monitors, has acquired UK-based TDL Sensors for an undisclosed amount. TDL provides tunable diode laser–based systems for gas measurements. “The expertise of TDL Sensors Ltd through tunable lasers (including cascade lasers) for the monitoring of high‐resolution gas concentration in industrial processes, combined with the expertise of Environnement SA Group in the monitoring of gas and particulate, will definitively help to anticipate the worldwide requirements for much lower emissions,” stated Environnement SA President and Founder François Gourdon. The management team and entire staff will remain with TDL.

TDL provides extractive and in situ systems. Applications include process and emissions monitoring. Environnement SA stated that it will release ultra‐low detection systems for hydrogen chloride emissions based on TDL’s technology.
