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? The indicator is available in both 500 ml and 100 ml bottles. The analyser is delivered with the 500 ml bottle set up and the scope of delivery includes the screw cap with hole and insert for the screw cap of the 500 ml indicator bottle. For operation with 100 ml bottles, the bottle size must be changed to 100 ml in the basic programming and the screw cap with hole and insert for the indicator must also be purchased. For Testomat 808 devices, the conversion kit (item no. 37580) must be purchased for the use of 100 ml indicator bottles, and for Testomat 808 SiO2 devices, the insert with screw cap and suction tube (item no. 37645) and the hose connector ø 3.5 mm (item no. 37643) must be purchased.
