MN PEHANON® indicator paper pH 1,8 - 3,8

PEHANON® pH measurement in colored solutions • PEHANON® is a special pH-test strips that unifies the pH-indicator and the reference colors on one strip and has the following advantages: • Any sample color has the same effect on both, the reference colors and the reactive pad. • This ensures unadulterated readings in colored solutions. • The user can be sure to get accurate pH-values. • An invisible hydrophobic barrier just above the top color field prevents capillary action of the test solution beyond. • The handle will remain dry and clean whatever the sample is. • Therefore the use of the strip is very safe. • pH-values can be determined without a separate color chart. • Workers and machinists can use single strips instead of complete packs with color chart which makes PEHANON® highly economic. • a pack of 200 strips • minimum purchase: 2 packs
