I bought couple of Analog RH meters from a ground floor shop at SimLim Towers for less than 10 $, few years back. I think they were seliing Digital type for around 15 $, then.

I have a pair if RH meters from Daiso, costs $2 each. One is reasonably accurate, the other is off consistently by 15%. They take about 2 hrs to eqilibrate. On the other hand, they are "cheap"
I use them when transporting scopes for overnight or longer deployments to make sure my dessicant is still working. Also, since the acceptable RH for optics is between 40-50+%, the inaccuracy is acceptable to me.

$2!!!?? I did see a thermometer (bought one fo my car) but did not notice the RH meter. I guess for $2, you can buy a few and then compare it to a proper one to pick the most accurate one. My only consolation is the reading on my new dry cabinet and my standalone meter is out by at most 1% with each other, so I guess I paid for the accuracy.
