Rapid Tests from MACHEREY-NAGEL
Unmatched pH testing enjoyment
Patented color fixed indicator
The patented pH-Fix technology ensures optimal usability of the test strips. During production, the indicator is fixed to the test paper.
The dye does not Wash out so clothes stay clean and samples remain pure.
Fast results
pH-Fix test strips allow fast pH testing directly at the point of interest. The easy Dip & Read procedure provides a reliable result within
10 seconds. Provided with a complete high quality color chart, pH-Fix does not need calibration and is immediately ready for use.
Easy and safe
For careful testing of dangerous, poisonous or aggressive liquids, pH-Fix test strips have the optimal design. The long plastic handle
effectively protects the user from contact with the sample.

PEHANON
Ideal pH test for colored samples
Accurate pH values
®
PEHANON is a special pH test strip that unifies the pH indicator and the color chart on one strip. Any sample color has the same
effect on both, the reference colors and the reactive pad. This ensures unadulterated and accurate readings in colored solutions.
Safe use
An invisible hydrophobic barrier just above the top color field prevents capillary action of the test solution beyond. The handle remains
dry and clean. The user is safely protected from the sample.
Economic test
PEHANON® allows the pH determination without a separate color chart. Workers and machinists can use single strips instead of
complete packs, which makes this test ideal for occasions, where many people have to perform the test in different locations.
pH indicator papers
Standard pH testing
pH indicator paper reels general purpose pH determination
pH indicator papers have been on the market for decades and are the appreciated standard for many applications. For each pH value
these papers show a single color which can be matched with the color scale at intervals of 0.2–1 pH uni
t.
Duotest improved accuracy
These indicator papers show two different colors for each pH value at intervals of 0.3–1 pH unit. This allows more accurate reading
and good estimation of intermediate values.
Tritest most precise pH determination
For most precise reading, these papers show three different colors for each full pH unit. This ensures optimal color differences and
allows good estimation of intermediate values.
