Great find I think:
I contacted Auber Instruments about converting their 30 stage Soak and Ramp Temp controller into a ramping humidity controller and got the following reply:
Hi,
Thanks for contacting us. Please visit auberins.com and order SYL-2342P
auberins.com :
http://www.auberins.com/index.php?main_page=product_info&cPath=1&products_id=5
OR
SYL-2372P:
http://www.auberins.com/index.php?main_page=product_info&cPath=1&products_id=264
(depending
on your load. If it is a heater, SYL-2342P is better; if it is a inductive
load, SYL-2372P is better)
*Leave us a note* during check out stating that you need modification for
humidity control. We can then send you an invoice of $43.93 for the price
difference. You can pay it directly with credit card or paypal account.
To find the shipping cost,
1) Add the item(s) you need to order into the shopping cart.
2) At the Shopping Cart page, click the "estimate shipping" button.
3) At the Estimate Shipping page, select the country that the order is
going to, enter the postal code, then, click "update" button.
4) You will get a list of shipping cost for different service by USPS and
FedEx.
BTW, the controller does not have computer interface.
Thanks,

This would allow you to ramp your humidity and temp programs simultaneously... I am thinking also that this could be done with one PID ... The Auber people are great for helping out also.
It seems we are gravatating towards manual control of curing but for those of us that are on the road a lot. we still need some sort of baby sitter
