Brass Analog Hygrometer

Pros: Accurate and Adjustable

Cons: None yet

I bought on Ebay for $6.99 and was not  expecting much. When it arrived I was impressed it is brass with a glass face. When I checked the calibation it was only 1% low it read 74% instead of 75%. After using it for three hatches it is still just 1% off. For what it is worth the seller says it is guaranteed to last for life.
