Description
Tritest – three indicator zones for highest precision
Tritest indicator paper has three different indicator zones on one single paper. The three zones guarantee optimal colour differences and safe determination of in-between values. Tritest indicator papers are available for a pH range from 1-11 and feature 1 pH unit increments.
Two options are available:
1) Tritest in a reel (without hydrophobic barrier). Width 10 mm, three indicator zones right next to each other, no partition.
2) Tritest L in a reel (with 2 hydrophobic barriers). Width 14 mm, three indicator zones, separated by two hydrophobic barriers. Even in strongly alkaline solutions, the colours of the zones do not mix.
