Thread: Humidity controllers

Strikes me that if humidity chez vous gets down to 20 often, your tops had better get used to it, cos once they leave your shop you won't be able to control anything. No?

I know that chemists used to sell evaporators, apparently they are useful for people with allergies,

Contrebasse, most guitar owners go out of their way (or should) to maintain constant humidity by, among other things, keeping the instruments in a case, by never leaving them in the car and perhaps using one of the humidi packs that you can put in you case.
The way a guitar top is made with a very thin top and braces glued across the grain means they will never get used to a big range in humidity, they just feak out and go flat when the humidity drops. Not a pretty sight.
What seems to be the best way to go it to build them at around 45% as the best average conditions. Hence the reason most try to control the humidity in the shop. You can imagine what would happen if I built them at 70% then put them into a centrally heated room at 25%.
Sebastiaan56, i have seen the personal humidifiers but what I need is one I can set a target humidity and forget it. And hopefully I want a combined unit becasue it does get humid here every now and again when it rains.

Then you're up for some serious bills Dom. Controlled atmosphere doesnt come cheap. The only reliable way is to build a room with all the sensors, regulators and stuff. If you are measuring the temp / humidity you have half a start but to do it automatically......

Thanks Seb, its actually not that expensive according to this link.

My problem is I have not been able to find this kind of unit in Aust.

We're moving back to Australia for good in December if you need something from here bought back let me know. I use a "plug in" dehumidifier in summer and a steam humidifier in winter. an a Radioshack wireless multi channel weather station with temp and humidity to kep an eye on it all. The only hassle would be the voltage. Now if you knew someone in Europe.....

Mitsubishi make a good domestic dehumidifier but for some reason they no longer import the machines into Australia. You can pick them up second hand on Trade Me in New Zealand.

I picked up my dehumidifier from a Queensland mob. Its a Chinese no name brand and not as good as the Mitsubishi but by playing with the settings in conjunction with an accurate hygrometer I manage to keep the humidity in the shop between 45 - 50%. During the winter months a ceramic panel heater keeps the shop warm and takes the load off the dehumidifier.

Well there you go, I only have practical experience with laboratory and industrial type situations and didnt know this kind of kit existed. You learn something every day!
