Pyreos sensors work across the mid-infrared and far-infrared where the unique signatures of many HVAC / refrigerant gases are found. Our products are the fastest amongst both pyroelectric and thermopile technology, allowing higher resolution and ultra low power consumption. ezPyro™, the world’s first surface mount pyroelectric device, is the smallest pyroelectric sensor available and is physically robust. We cover many refrigerants including historic substances covered in specialist applications. Contact us if we do not cover your needs.
