Pehanon, Test Strip, 3.8 - 5.5 pH, M. Nagel

 Test strip for pH measurement which unifies the pH-indicator with the reference pH color chart on the same strip.  
pH values can be determined without a separate color chart. They provide precise pH measurement of solutions by using single color change.
The user can be sure to get accurate pH values at all times.
Fast measurement results are guaranteed since they do not require an addition step of matching the pad color with a reference color scale.
The handle will remain dry and clean by the invisible hydrophobic barrier.
200 pieces strip is packed in a clear polystrene box for hygenic storage and for easy dispensing.
