About ENVEA TDL Sensors
TDL Sensors was founded in 1999 and spun out of the Department of Chemical Engineering, University of Manchester, to develop a tunable diode laser based gas analysers. In the following years, TDL Sensors have developed measurement solutions for the glass coating industry, ultra-harsh processes, enclosed atmospheres for the protection of personnel, air quality monitoring and for the oil and gas industries.
In 2016 we became part of the Environnement S.A. group of companies. Environnement S.A. is a leader in the field of continuous environmental pollution analysis systems.
Using laser absorption spectroscopy TDL Sensors can measure the gases that are important to your process, application or, even, your and your co-workers well-being and safety. Small gas phase molecules, including oxygen (O2), carbon monoxide (CO), carbon dioxide (CO2), moisture (H2O), hydrogen chloride (HCl), ammonia (NH3), hydrogen fluoride (HF) and methane (CH4), can all be measured at rates of up to 10 Hz to provide rapid, real-time monitoring.
As laser absorption spectroscopy is a high-resolution technique, and our laser wavelengths are carefully selected, the measurements are specific and free from interfering background gases, which is often a major limitation of other gas measurement techniques.
Our analysers are simple to set up and have an easy to use interface so that the user can be collecting data almost immediately. There is no need for carrier gases or consumables and, consequentially, our laser gas monitors have a low cost of ownership and require little maintenance.
