• Fixed dyes – No bleeding into solution
• Ideal for turbid or weakly buffered solutions
• Test 0-14 pH range with a single strip
• Strips also available for narrower ranges
Strips provide accurate colorimetric pH indication without bleeding into solution. For greater accuracy, immerse indicator strips for prolonged period when testing weakly buffered solutions. Made of a plastic strip on which a dye is covalently bound to the paper carrier. Choose from universal, intermediate or narrow range strips.

Sensitivity
Universal: 1 pH unit
Intermediate: 0.3-0.5 pH units
Narrow: 0.2-0.3 pH unit
