They usually list in around 5% accuracy and are not as directional as a pitot. Gut feeling is that the hot RTD resistance measurement would be more robust than a low static dp, and thus more likely to be accurate between trips to the lab.
Quality means a lot with instruments though. You gets what you pays for.
