You need to crack open an egg on a leveled plate of glass after weighing it in order to measure the haugh unit of an egg.
Then you need to measure the height of the albumen with the albumen height gauge with a distance of about 1cm to the yolk.
The formula for the calculation of Haugh-Units is:
While:
- HU = Haugh-Unit
- h = measured height of the albumen in mm
- w = mass of the egg in gramm
The calculation is automated within our software.
You can read the data out of the table alternatively.
