Pyreos sensors can be used to detect and measure substances in gases, liquids and some solids with great precision.
In gases and liquids the composition can be measured very accurately. For Pyreos gas detectors, see here. For liquids and some solids, we offer broad detectors (Linear Arrays) and precise targeted detectors. These are listed below.
Our products are the fastest available giving higher resolution and lower power consumption. There is no “warm-up” time. There are no moving parts so customer systems can be more robust.
The range of Pyreos targeted detectors is growing all the time so if you don’t find what you’re looking for then please contact us.
