Multi Point Calibration For The iSpindel - "Easy Method" - DIY Digital Home Brew Hydrometer [4K]

This video shows how to calibrate the iSpindel to create a polynomial formula that will ensure super accurate gravity readings in your home brew fermenter. This video shows the easy method using a sugar wash solution and additional dilutions, and in future videos I will show the "fast ferment" method which increases accuracy even further. Once you have calibrated the iSpindel, you are ready to connect it to the services that you are wanting to use for it such as Brewfather, Ubidots, Fermentrack or BrewPi / BrewPiLess. I have videos coming out on connecting the iSpindel to these services so subscribe to check them out!

The iSpindel is a digital hydrometer that lets you wirelessly see your home brew fermentation temperature and specific gravity. With built in WiFi, the iSpindel can connect to apps such as BrewFather to graph the progress of your ferment and be accessed anywhere in the world! The iSpindel can also be used to tie in with other hardware such as BrewPi / BrewPiLess in order to build fully automated fermentation temperature controllers.
