Review: just the job we use a few of these and ... - just the job we use a few of these and always does what it is supposed to do ie tells us the PH of the water leaving the factory
Review: It does its job but it doesn’t last - The pH meter does its job but it lasts only a couple of months. Being that the probe can’t be replaced, I think it’s expensive. I wish the readings were more stable as well cause it takes time to show a reading and even so it keeps changing.

## Questions & Answers

**Q: How would it test pH in a person?  How can we do it once purchased?**
A: I am not sure if you can use this to test the pH if a person.  Perhaps by putting it in sweaty skin.  You should call manufacturer to see if they can answer your question.

**Q: can i use this meter for cheesemaking?**
A: Don't see why notCheesemaking websites list similar ones, maybe less precise than this but same technology

**Q: Can I use for stiff dough?**
A: Yes you can.  This can read liquids and solids.  I use mine to measure the ph of cheese curds and whey.

**Q: I have a very similar meter but it is "ph110" instead of "ph100." will this "ph105" sensor work with the "ph110?"**
A: Yes the PH105 is the replacement pH electrode for both the PH100 and PH110.

*by C***S on 11 December 2015*

just the job we use a few of these and always does what it is supposed to do ie tells us the PH of the water leaving the factory

### ⭐⭐⭐ It does its job but it doesn’t last
*by M***M on 25 March 2024*

The pH meter does its job but it lasts only a couple of months. Being that the probe can’t be replaced, I think it’s expensive. I wish the readings were more stable as well cause it takes time to show a reading and even so it keeps changing.

### ⭐⭐ Over-priced, flimsy and hard to maintain
*by A***R on 8 June 2025*

Doesn't last and impossible to find replacement filler solution. The cost of a new electrode (if you can find one) is more than the cost of a a new pH meter. It's over-priced and has poor support after sale.
