That kind doesn't work in water. It's not designed for it. I have a cheap one I got from Amazon for water testing, but from what I've read here and on r/Hydro they're not terribly accurate and need calibrating all the time. It's not available anymore but you can find similar ones all over Amazon, also for cheap. (https://www.amazon.com/gp/product/B075J888J7) Just search for similar ones if you don't want to spend a bunch of money for starting out.
