Macherey Nagel 90414 Pehanon strips pH 2.8 - 4.6


Macherey Nagel PEHANON pH indicator strips for the range 2.8 to 4.6. Steps are 2.8, 3.1, 3.4, 3.6, 3.8, 4.0, 4.3 and 4.6. 200 strips. These strips are designed for measuring pH in coloured solutions. Colours for all the pH steps are included along the strip with a zone in the centre for the actual test. A coloured solution that affects the indicator colour will also change the reference pads by the same amount. So the actual pH can be estimated as easily as it can be in a clear solution. PEHANON test strips work best in buffered solutions. For weakly buffered or unbuffered solutions try to use pH-Fix test strips. These strips are especially suited to testing pH in preserves, chutney, jams & sauces where the food colour would normally interfere with the colour on the test strips. For food safety, preserved food needs to have a pH of below approx. 4.6.
