I just bought an inexpensive Chi control. Seems to be working pretty good for the price (still tinkering with it a bit). Some of you guys who have some experience let me know your techniques. I have a digital thermometer with a probe I have run into the fridge to monitor the temp. I need to read the manual and find out if the probe can be submersed. If it can should I run the probe through the airlock port into the beer to get a more accurate reading, or does it work fine to just tape the probe to the side of the bucket/better bottle?
