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. To use 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 (item no. 40143). Where can I find the safety data sheet? The safety data sheets can be found in the online shop (www.heylneomeris.shop) under the menu item – Service/Help – Downloads Safety Data Sheets. How can the indicator be disposed of? Disposal instructions can be found in section 13 of the safety data sheet. Disposal must be carried out in accordance with official regulations. Can the indicator still be used after the expiry date? The indicator can no longer be used after the expiry date. After the expiry date, accurate measurement results can no longer be guaranteed. What is the optimum storage temperature for the indicator? Section 7 of the safety data sheet contains all relevant information on storing the indicator. The recommended storage temperature should be between 15-25°C. Device warranty / guarantee Measurement errors when using third-party indicators!
