Is the gravity reading from a Tilt Hydrometer adjusted for temperature?

The reason I ask is threefold.

  1. I watched my gravity readings go up from 1.039 to 1.043 as I cooled my wort before I pitched.
  2. I noticed in the System page of my TiltPI, it says SG 15C/59F (default)
  3. When I cold crash, the gravity readings go up. When I enter the temperature and gravity reading in a hydrometer temperature adjustment calculator, the gravity is the same as before the cold crash.

It seems beyond reason that this device would need to be adjusted for temperature, since it is both a hydrometer and thermometer, but that appears to be the case.

Beer, like most liquids becomes less dense at higher temperatures but this effect also depends upon the alcohol content so it would be hard to reliably calibrate out. In reality I would strongly advise that hydrometers based on the tilt principle are great for showing variations in SG but are not particularly reliable as an accurate measure of absolute gravity. Therefore they are best used as a means of keeping track of the progress of a fermentation from day-to-day, but when it comes to establishing the final gravity of your brew it's best to use a hydrometer.
