General description

The MQuant pH tests are suited for all media in environmental analysis and in industrial in-process controls. Our special method of manufacture gives the pH indicator strips decisive advantages over the indicator paper: since the indicator does not bleed, the strip can be left in the measurement medium without contaminating it. Using these test strips is fairly easy, the pH value is measured semiquantitatively by visual comparison of the four reaction zones on the test strip with the fields of the color scale, perfectly matching the reaction color. The clever Safetyedge boxes allow for safe storage and convenient withdrawal of the test strips. For tests for other parameters that require a specific pH range of the sample (e.g. Spectroquant, see instructions of use), we recommend the use of MQuant pH test strips as pre-test.
