Electronic tester

[Sidemoves]

Are there any electronic water testers that are actually reliable and durable?

In a word - no.

Unless you have VERY VERY deep pockets.

What’s the cost? Have a link you can share?

No idea. I don't have the funds or need for lab quality testing instruments. And I don't have the time to keep them all properly calibrated.

I use drop testing using Taylor reagents. These drop tests are more than adequate for both residential pools and most commercial pools when used consistently in a proper manner.

What’s the cost?

Four figures for the unit and five to ten dollars per test. Similar accuracy as a TF-100, marginally more precise, and not all that much less work.

I do not have a link to share because the equipment is sold through salespeople to large accounts.

I have an electronic photometer tester that works with reagent tablets or drops. I use tablets because it's more convenient (not the fast dissolving kind). It's not lab quality but it's reliable enough for what I need. It was about 100 euros:

I've had pretty good luck with my WaterGuru, but I still check with a dropper test once a week to confirm. If the WaterGuru goes bad and reports everything is OK when the water isn't I won't have any other warning.

I do get the occasional weird result (like a PH 6.5 the other day? I know that was wrong as I hadn't added any acid to the pool) but I discard those results and look at what it is the next day.
