I bought digital PH meter before, but it didn't seem to last long before no longer working, and I hate having to recalibrate using chemicals, which over time can change PH. Perhaps there is a really good litmus test that is 2 phase? One for wide range and specific range tests?

I've never come across something like that. I simply remember them as blue or red 😄

Stick to the digital ones. They're far superior to paper 👍

Are digital meters used professionally or is paper with color guides the main thing?

Both. When we're doing analytical measurements, we use the probe, and when we want to know if something is alkaline or acidic, we simply use the strips.
