About ELT SENSOR ELT SENSOR is a gas sensor specialist featuring world-class technologies. With a vision of ‘Create a Smart World with Sensors’, we aim to use sensor technologies in such a way as to provide a safer and comfortable environment for the world. We have original patented technologies in the area of NDIR (Non-Dispersive Infrared) type measuring principle which is designated as a main testing method in measuring CO2, CO and CH4 throughout the world, as well as knowhow that has been accumulated through an abundance of experiences. Through leveraging this expertise, we can develop various kinds of gas sensors with high accuracy and even mass-produce the developed products at a world-class quality. Currently, NDIR gas sensors that measure CO2, CH4 and others are being mass-produced and exported to approximately 40 countries around the world. We have also developed other NDIR sensors that measure CO, CO+CO2 and ethylene. As a sensor specialist that provides a successful start in IoT (Internet of Things) frontier, ELT SENSOR hopes to cooperate with customers in order to provide the best gas sensors and environment measuring solutions that are fully optimized to their needs of them and help to create a better world.
