    Field work

    Posted by Nancy on Aug 5th 2019

    I needed a soil pH tester in an emergency situation before going to do fieldwork in the Caribbean. The salesman from QA was fantastic in helping me choose the correct meter and then had it overnighted to my house. This meter was great in the field and I was quite happy with its performance.
