Strong chiller you have , great score ?

thanks

Hello Dr.Antoine, is it a normal freezer or is it modified? What is the actual temperature of the water inside the freezer?

I wanted to know the temperature of the antifreeze inside the freezer, in image #4 below and on the right it doesn't look very good but it reads at -38, is this true? And my other question is if you modified the freezer so that it reaches that temperature or is it standard?
