I’ve got a Taylor K-2006 test kit. While getting the appropriate water sample size isn’t hard, in the past I’ve seen some people comment on here about a measuring device that makes it faster and more consistent. From what I remember it’s a cylinder that has an inner cylinder that allows you to set the 10, 25, or 44 mL test volume. That way you’re not pouring out of the Taylor beaker to get the desired volume of water. Does anyone know what this thing is called? I can’t seem to find details on it. Thank you.
