Discrepancy between probe temp and thermometer temp...
So, when you guys use charts like this:
To establish proper temperatures and psi settings, do you rely on the temperature from whatever digital or analog probe you're using on the thermostat?
I've had instances where there's been a 4-5 degree difference between what my probe is reading and what the small little analog thermometer that I placed in the freezer is reading. Am I getting inaccurate thermometer readings from the small analog one because it's sitting right on the cold floor of the freezer (or sometimes the hump)? Normally if the probe reads 45-47, it will read 42.
In a situation like that, I'm having trouble deciding what to put the PSI at because I don't know if the beer in the keg is closer to 42 or 45. Currently it's at 13 psi, and I don't have foaming issues or anything like that, but I want to make sure I'm shooting for the middle for ale styles of beer and not undercarbed.
Trust neither, pour two glasses of beer and check the second one with a trusted digital thermometer, I use my mash thermometer. Then adjust your controller accordingly. Although a 3f to 4f variance isn't really much to worry about, it will hardly change your final carbonation.
I gotcha, I'll try that tonight - thanks
