I got this one from the same maker.

You can buy replacement probe if you need to. It comes with 4.0 and 7.0 test solution and storage solution. It is .00 accurate.
It is pretty quick. I have it 1/2 a year and so far so good.

That one looks really good. Thanks. It doesn't cost much more than a replacement electrode for my current Hanna meter. Encouraged by your testimonial, I think I'll consider this when my electrode reaches the end of its life. I've heard good things about the Apera instruments. The one thing I like about Hanna is the renewable fabric junction. But while it is renewable, I suspect it may not be ideal at its best.
