Decent hygrometers? (humidity measures)

[Wingbeats]

Hello everyone!
I ordered an Animal Plastics T8 cage for my rainbow boa a while back, as she is outgrowing her Ziplock tub. Humidity is easy to see in her tub, as the heavy condensation on the lid tells me the humidity is fine (the analog hygrometer broke long ago, lol).

However, for the incoming T8 cage, I want to keep the humidity measured. Looking on Amazon, it seems many hygrometers for reptiles have poor ratings. I need something that performs well with high humidity, since rainbow boas require 70% or higher.

Any good hygrometer recommendations? Something with a probe would be ideal, so I can read it outside of the cage easily. I'm willing to spend a good amount to get something that works.
