Macherey-Nagel PEHANON pH test strips

Click2Contact

PEHANON is a test strip designed for measuring pH in coloured samples. Both the pH indicator and the reference colour chart are unified onto one test strip, so any colour within the sample has the same effect on both the reference colours and the reactive pad.

The test strips do not require a separate colour chart, saving time for workers in production. They also have a built-in hydrophobic barrier to prevent migration of the sample toward the user’s fingers, making the product safe to use and free from contamination.

It’s important, for food safety, to monitor pH levels to prevent the growth of harmful microorganisms in food and beverage. pH is also crucial for the development of flavour; for example, the lower the pH, the more sour the taste.

Suitable for testing pH in coloured samples such as soft drinks, sauces and wine, the test strips are designed and manufactured in Germany by Macherey-Nagel. There are 14 different measuring ranges available. Each pack contains 200 test strips with a shelf life of 3 years from date of manufacture.
