Double pump head for Testomat® 808 SiO2

Dear customers, please note that the calibration of the Testomat® 808 SiO2 can only be carried out with silicate-free water. Therefore, please use the silicate filter cartridge specially developed for this purpose when replacing the double pump head (art. no. 40395) and the associated pump adjustment.The cartridge filled with the special resin is inserted into the sampling line of the unit before the inlet and removed again after the adjustment. The pump replacement instructions describe the use of the silicate filter, storage conditions and shelf life. After the first use, the filter can be used up to 10 times within one year for balancing. After one year, the filter must be disposed of. Frequently asked questions What do I need the silica filter cartridge for? The silicate filter is intended for the calibration of the Testomat® 808 SiO₂ after the pump head change. When is the cartridge inserted? During the exchange of the pump head and during the device calibration. Why is the cartridge necessary? It removes silicate from the water and prevents false measurement results. Where is the cartridge installed? Before entering the sampling line of the device. Can I reuse the cartridge? Yes, it can be used for multiple comparisons. The filter can be used up to ten times within a year for calibration after the first use (applies to SiO₂ concentrations of up to 1 mg/l. At higher concentrations, the usability of the filter is correspondingly reduced). The filter must be disposed of after one year. Do I have to have the cartridge permanently installed? No, it is only used for the comparison and then removed again. What should I consider when using it? Please read the operating instructions "Replacing the pump head on the Testomat® 808 SiO₂" carefully.
