Mettler Toledo DL18 Titrator
The Mettler Toledo DL18 Titrator is a complete analysis system for determination of water content using the karl fischer method. Its easy, dialog format operation and automatic use of sample weight for calculation of the result in per cent or ppm make it an excellent instrument for routine analysis. Dispensing of solvent and evacuation of the hermetically sealed titration vessel by means of a membrane pump have also been automated in this compact instrument.
