Yes, we have a couple of options for measurement in the duct. You want to have a look at GMP252, which is a probe type instrument (https://www.vaisala.com/sites/default/files/documents/GMP252-Datasheet-B211567EN.pdf). This is a heavy-duty product that can take high humidity levels. We also have a duct transmitter, the GMD20 that is intended for this type of measurement (https://www.vaisala.com/sites/default/files/documents/GMD20-Datasheet-B211432EN.pdf). High air speed doesn´t affect the measurement of CARBOCAP sensors.
