Taylor Technologies 6190 SampleSizer 10 ML/25 ML

I do a lot of water tests on my pool so I'm constantly filling that test tube to either 10 ml or 25 ml levels. This makes it instant, easy and perfectly accurate. It is insanely well made with (I think) machines aluminum and is solid in your hand. If you do a lot of tests this will save you time and effort.

I absolutely love this item. It makes my life a lot easier when checking my pool chemicals. This item saves me time and money and will last for years as it is solid. What can I say other than this item works well and the size is small.

Works well, always does 10mm exactly. Saves time be4 i was pouring slowly via Leslie'sPool drip tube. Not sure why other 1 star reviewer claims it doesn't measure exact. Note: you'll need the Taylor 9198 sample tube (doesn't work with others as they are slightly different sizes)

This really helps simplify managing your pool, cannot believe I waited so long to get it. I thought it was high priced, but after receiving it I do think it is worth it, very high quality material. This will last forever.

This device makes getting an accurate test sample measurement. I'm just not sure why a piece of metal should cost $30.

Very well made; solid aluminum. Reduces time to test appreciably. As long as you can test where some spill over is not a deal breaker (I always test near the kitchen sink) this is a great time saver.

A little pricey, but once you get it you see why. It's very well built. The way to use this may not be super obvious at first. You don't want to leave it in while you fill it. You fill the tube with water first, then take the end that you are wanting to use, and plunge it into the tube. It will displace exactly enough water to give you the accurate final measurement. Once you get your first measurement and get an idea of the levels in your pool(s), you should switch from the 25mL to 10mL in order to save test chemicals.

Worth the money. Makes measuring out water for testing so much simpler.
