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.
