These quat test strips measure residual QAC levels from 10-100ppm in liquids or on the surfaces of utensils; only $11.95 Pack/100.

Note: the directions on the bottle are for testing a liquid. See below for important information.

Details

To test for residues simply wet the strip's testing pad with water (deionized or distilled if available) & press against the surfaces of fruits, vegetables, cutting boards & utensils, etc. for at least 10 seconds & then compare against the color chart.

Levels less than "10" ppm are impossible to determine but current rules for organic certification call for "0" ppm. This is next to impossible & unrealistic since water alone causes a reading of 10ppm. Read more in our blog on what 10ppm really means when measured on a knife or other surface.
