Testomat Indicator TC2050 500 ml Carbonate Hardness Measurement for Testomats The Testomat Indicator TC2050, 500 ml bottle, measures carbonate hardness in water. Carbonate hardness (also called temporary hardness) describes the amount of dissolved calcium and magnesium carbonates in water. It is a critical parameter in industrial water treatment, as it significantly affects the water's buffering capacity. Excessive carbonate hardness can lead to scale formation, deposits in pipelines, and efficiency losses in heat exchangers. At the same time, carbonate hardness is an important control parameter for softening and dosing processes. The Testomat Indicator TC2050 allows reliable, automatic monitoring of carbonate hardness through a precise color reaction. It is especially suitable for process and utility water with a pH value > 4 and supports stable and safe process control. What values can be measured? 0.50–5.00 °dH, resolution 0.50 0.90–8.96 °f, resolution 0.90 8.9–89.5 ppm CaCO₃, resolution 8.9 0.18–1.79 mmoI/I, resolution 0.18 Where can the indicator be used?

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: Indicators consumption calculator - Heyl Neomeris What sizes are available for the bottles and is there anything to bear in mind?
