What's the best digital psychrometer under $200? I know they are not the most accurate but Im a maintenance tech for a company that requires rh%, wb, and split readings on each job. So I just need to be close. The one I have now is a AMPROBE THWD-3. I've had no problems with it until recently(giving unusually low rh and wb readings). So Im looking to pick another one up asap. The only gripe I have with the amprobe is the amount of time it takes to adjust its readings. This may come with the territory of digital psychrometers but if there is a better one out there. Let me know. Thnx for the replies in advance. I've read this site from time to time over the last year but just joined today.
