RH Meter Without Sleeves

[Ernesto]

Seems there is someone out there that is making an Rh meter that does not come with a sleeve of any kind. He is saying that one does not need a sleeve of any kind and if you wanted one simply roll up some foil tape.


Personally I have never heard or seen any reusable rh probes that does not utilize a sleeve of some kind or a stop gap rubber seal like on the old ones. He says and I quote " have not seen any data regarding the difference in RH readings made with and without sleeves. If any exists I would certainly welcome the opportunity to evaluate it. Of course the effect of a sleeve can be easily and cheaply achieved by using a metal foil tape formed into a cylindrical shape and placed into the drilled hole."

Don't want to name names but this guy does seminars and charges plenty. Knows lots of wood science though.

Is he correct or not?
