Indicator is a key factor in measurement technology
Indicators and indicator chemistry enable color comparison or matching by titration into a water sample.
Online titrators are measuring instruments that enable very good measurement results to be objectified by means of the color change. The measurements are comparable to laboratory results. Heyl indicators have stood for high-quality chemical titration for well over 60 years.
For testomats the original indicator is always recommended. The reasons are easily explained:
- not every indicator (or reagent) works with the same chemical composition, for example.
- the manufacturing specifications are tested and verified in-house, therefore e.g. the shelf life is also assured. (Many competitors state higher shelf lives. - "But who leaves his indicator lying around for almost two years to then check its effect?")
- the entire system is geared to Testomat® use and, above all, thus enables optimized consumption with the best results.
- third-party indicators reduce the warranty period to the shortest legal warranty period in the world.
- a chemical analysis of the indicator can lead to the conclusion that "wrong" indicator was used and an equipment or work malfunction is due to it.
- neither the ingredients of the indicators must be the same, nor their proportion in the particular indicator.
Often the change is expressed by a color change.
In addition to decades of experience, we have our own chemistry laboratory and chemical development department, which consistently ensures the highest quality of indicators.
Chemistry has been our business from the very beginning and thus for more than three generations already.
