Test ketones and ph in one strip!
Easy to use. Unique strips test both ketones and ph. Improved strips over original have a separation space so there is less chance of blending together which can distort results. Be sure and store in cool, dry place. Humidity can affect the strips. Container has half of strips in sealed foil packet to remain fresh. Don't open the second packet until the first batch is used up. Otherwise they get old and may not work.
