Litmus Paper pH Test Strips 4.5-8.0 for Urine, Saliva & Body Fluids (80 Strips)

Precise Litmus Paper pH Test Strips (4.5-8.0) offer a fast, affordable, safe, and accurate way to measure the pH of saliva, urine, and other bodily fluids. Conduct convenient at-home testing; these pH strips are incredibly easy to use. Unlike universal litmus paper, these strips feature a narrow 4.5-8.0 measurement range with a fine 0.2-0.3 increment, ensuring highly accurate results. Designed for urine, saliva, and other fluids, these strips boast high color contrast. Each batch is meticulously calibrated for concentrated solutions by an accredited biochemical science and technology laboratory in China. The reactive chemicals within the strips interact with sialic acids present in mucous membranes, internal organ tissues, salivary gland secretions, and blood plasma, resulting in a color change reflecting the acidity/alkalinity of the sample. Use these strips to determine the normal pH of urine and saliva, assess overall body acidity, and proactively address potential health issues. Instructions: Tear off one strip, immerse it in the liquid for 1-2 seconds, then place it on a dry, clean surface. Within one minute, compare the strip’s color to the color chart and select the closest match.
