Water Tester Supreme!

I LOVE it. I tested my water before and after distillation. Super easy to use, I think it's extremely accurate because my burner is by no means an expensive high-end science burner. This is a simple, inexpensive water still and there was a significant difference between pre-distillation and post-distillation. My distilled water seems extremely low in contaminants, which makes sense considering the water is picking up things from the container, air, etc.

Pros
  • pH meter
Cons
  • Not as thick as other options
