Two frame rates in the catalog. Fluke lists each model in both 9 Hz and 27 Hz versions, under two separate model codes, with the same sensor and the same optics. Both versions are distributed in Europe. It's up to the buyer to check which one they're ordering, since retailers don't always make the frame rate obvious. Values used here: the 27 Hz version.

A narrow 28° lens for 256 pixels. 1.91 mrad, a spatial resolution few devices at this level achieve. The trade-off is the narrowest field of view in the comparison — you need to step back to frame a whole facade.
A lighter version of the TiS75+. No dew-point calculation, no radiometric video recording, 3 cursors and 3 zones instead of 5.
Weight. 2.27 kg, double the heaviest of the other devices in this comparison and six times the HIKMICRO B20. Worth factoring in for a day of overhead readings.
On-screen transmission correction, in addition to emissivity and reflected temperature: a full correction chain, rare in this comparison.
