Hi . I just "discovered" this group and have a question .

I see many versions of soil PH meters for sale from about $20 to $200.

Has anyone used these, do they work well, and are there any good
tips on operating them properly ??

Yes these work well.

Also, has anyone cross-checked their PH meter with litmus testing to
see if it continues to be reliable even after the sensors grow old ?


Litmus papers only test for acid or alkaline. You can use pH test
papers.

Thanks for any discussion on this.
