Review on Magnetic Stirrer Speedstir Start Up Batteries by Justin Dorsett

Generally works well and makes testing much easier than rotating the sample by hand, but there are some minor issues: Sometimes the sample tube rotates and can tip over, you have to hold it in the base. Needs storage space for the box to keep it together or better yet built into the box with the K-2006 pool test kit. The sample vial requires a 44ml mark for the PH test, I scribbled a mark on it but close to the top. UPDATE After a few months I also noticed an inconsistency in the chlorine test (Taylor K-2006). When I work with Speedstir I can get 4, but when I do it at the same time with the same sample, same tube, just by waving my hands I get 5. Very strange, I have many times and both ways tested the results are always the same. I can't explain why the different results. With other tests I get the same results anyway. It's possible that more air mixed with the sample somehow affects the chlorine test, but with Speedstir it's always lower and I don't know why?
