Review on Longang Digital Temperature Function Included by Cody Nordlund

They attach to anything. With an empty bag or bucket, press the zero button and then put something in the bag. you will gain weight They are much more compact than floor scales but work just as well. You just have to know that it measures gravity. So when you lift something, it adds that acceleration to the top weight it's freezing on. So lift slowly if you need super precision.
