Häufige Fragen
How long does the indicator/reagent last?
The shelf life of an indicator is printed on the product label for each batch. In accordance with our terms and conditions, we deliver with a guaranteed minimum shelf life of 7 months.
How much indicator is used per analysis?
When it comes to indicator consumption, a distinction must first be made between TH indicators (e.g. TH 2005, 2025, 2050, etc.), which are used for the Testomat ECO, Testomat EVO TH, Testomat 2000 and Testomat Limit LT analysis devices, and the indicators for the Testomat 808 (300 series indicators, e.g. indicators 301, 305, etc.).
The indicator consumption per analysis for the TH indicators is directly related to the limit value to be monitored. The higher this is, the higher the indicator consumption. For the Testomat 808 indicators (300 series), consumption is approximately 80 µl per analysis.
By entering the operating data (analysis interval, limit value, etc.), the exact consumption or indicator requirement per year can be determined using our indicator consumption calculator:
