PEHANON®
pH determination in colored samples
PEHANON® test strips unify pH indicator and reference color chart on one strip. Any sample color has the same effect on both, the reference colors and the reactive pad, allowing unadulterated pH reading even in colored solutions.
Safe testing of hazardous samples
An invisible hydrophobic barrier just above the top color field prevents migration of the sample. The handle remains dry and clean and the user is safely protected from contamination due to capillary rise.
No separate color chart needed
PEHANON® test strips can be read without a separate color chart. Workers in production can use single strips instead of complete packs making the product very economical.
