Our ultrasonic waveguide technology is a patented solution, developed from research originating at IIT Madras. It represents a significant advancement over conventional temperature sensors. Unlike standard thermocouples or RTDs, which are highly sensitive to environmental conditions and often fail at high temperatures, our technology can deliver accurate "skin" temperature measurements directly at the material interface. This ensures precise readings even in extreme industrial conditions such as refineries, power plants, steel plants, and chemical reactors.
