pH–Fix indicator strip enables fast and reliable determination of pH values in water–based liquids and stands out for its particularly user–friendly handling: simply dip it in and read the result. The brilliant color scale on the test strip container ensures precise color matching, making pH determination especially intuitive and accurate. At the same time, the extra–long, hydrophobic plastic handle reliably protects users from contact with hazardous or aggressive samples and allows measurements even in deep or hard–to–reach vessels—ensuring maximum safety and flexibility in everyday work. Thanks to our patented technology, the indicator remains bound to the test field, so that no bleeding into the sample can occur and contamination of the sample is reliably prevented. The practical PT container can be easily opened and closed with one hand and stands securely on the work surface, making handling even easier. The test strip can be evaluated with the included color scale as well as instrumental with the QUANTOFIX Relax strip reader. In addition to a convenient measuring procedure, this also offers automated and digital documentation of the results. Whether in laboratories, schools, forensic science, or a wide range of industrial sectors—pH–Fix indicator strips are the standard method for simple, rapid, and cost–effective pH determination.
