With this professional instrument, you can easily determine the frost protection of your coolant, essential for preserving your engine in cold conditions. ### Automatic temperature correction Thanks to the built-in thermometer, the Coldomat 5100 automatically adjusts the measurement based on the fluid temperature. This ensures accurate results, whether the fluid is warm or cold. ### User-friendly design - **Glass cylinder with thickening** : Provides durability and a firm grip during measurement. - **Large float with clear scale** : The easily readable color and number indicators make it simple to interpret the measurement results. - **Manual in 20 languages** : The packaging includes a comprehensive user manual, so you always know how to use the device correctly. ### Technical specifications - **Temperature range (at 20°C)** : –2 to –41°C - **Temperature display** : 2 to 74°C - **Suction volume** : 40 ml - **Total length** : 360 mm - **Suction hose length** : 200 mm - **Weight** : 180 g ### Easy operation 1. **Preparation** : Remove the suction bulb from the glass cylinder and take out the float. Moisten the suction bulb and hose slightly for easy assembly. 2. **Filling** : Squeeze the suction bulb and immerse the antifreeze tester in the fluid. Allow the fluid to be drawn in until the measuring chamber is completely filled and the float floats freely. 3. **Reading** : Check the temperature on the thermometer and read the fluid level on the scale from A to K. Use the supplied table to determine the frost protection in degrees Celsius. With the GEFO Coldomat 5100, you are assured of a reliable and accurate measurement of the frost protection of your coolant, contributing to the optimal performance and lifespan of your engine. ## Breadcrumbs -
