What is the most accurate kit to use to check the PH levels?

The majority of kits work well enough to give a good idea of the pH.
Just be a little careful of the ones with metal prongs that stick into the
soil, and you may find they measure moisture and light levels too. I've seen
them a little innacurate.
Pretty much can't go wrong with the ones where you add a liquid and powder
to the soil sample.
Always remember take samples at the root depth.
