PEHANON® are special pH test strips that unify the pH indicator and the reference colours on one strip. Any sample colour has the same effect on both the reference colours and the reactive pad. Users can be sure to get accurate readings.

• Sample colour has no effect on the results
• No accessories needed - always ready to use
• Highly economic - colour scale on every single strip
• Safe usage due to hydrophobic barrier

An invisible hydrophobic barrier above the top colour field prevents capillary action of the test solution, so the handle will remain dry and clean. pH values can be determined without a separate colour chart.
