3 Kegland Rapt devices have different temp readings

[BandonBrewingCo]

Top left corner are the two temp probes and the yellow cap of the pill (unplugged) so all reading from the same place.

How the hell am I meant to calibrate???

After some time after plugging out the pill is coming down to closer to the probes.

Still have:

BLE: 22.0
Rapt temp controller probe: 21.0
Pill: 22.8

The first 2 are consistently 1C apart which is interesting. I suspect the pill will meet one of them given enough time to cool down

What is the specified accuracy of each one, and what is the standard you're using for the reference?

Ice water is what I have seen typically used to calibrate a thermometer used for brewing. Check the device manual as there are may be specific instructions regarding how to set up the ice water.

Also, measuring devices have accuracy values. For instance + or - 1 degree F. If you have two thermometers with that accuracy, and one reads 40.5 and the other reads 39.8, they are essentially the same reading since they overlap. The first one is actually 39.5-41.5, and the second one is 38.8-40.8.

The temperature on the pill has always been dubious. Especially when you are directly connected to it to access the calibration portal. My theory is that the extra workload on the processor heats up the airspace inside the tube and then will throw it off while attempting to calibrate.

Also, keep in mind that the Pill can take a while to equalize. The case can insulate it to a degree.

All very helpful tips. Thanks everyone!

Ya they even say that themselves in fairness
