I hope so. I'm going to do an extended salt test with another hygrometer. I'll add the results after its completed to see if it keeps the 5% differential. Anymore, I'm skeptical with any hygrometer I purchase. They seem to give me varying results.



EDIT: I guess I should add a little more about the unit. It is really a nice little device. Small but the numbers are big and easy to read. It can support up to 3 remote devices up to 100ft. The devices are fairly small as well, could easily fit in most humidors without sacrificing too much room. Really my only complaint is the accuracy of the humidity sensor.
