The Ricca Chemical 8881-1 single-use pH test strips are for measuring pH from 0-6. The indicator is fixed to the test pads to help prevent dye from bleeding into the sample. The package includes a color chart for matching the color and position of the test pads. Each strip has a long plastic handle that reduces contact with the sample. They come in a pack of 100.
