Measuring and controlling the amount of water in oils is of considerable economic importance to the industrial community, particularly to the crude oil and electric power industries. Water content determination by Karl Fischer titration is no longer restricted to being used by a chemist in a laboratory – now the technique is used by engineers, plant operators, tanker drivers, distribution/maintenance engineers and other non-laboratory personnel.Karl Fischer titrations can now be performed in many different locations such as the tailgate of trucks, mobile laboratories, offshore installations, tankers, engineering workshops and dockside cabins. The Aquamax KF Portable is a truly mobile version of the very successful Aquamax KF Coulometer which includes Low Drift Cell twin port glassware as standard. Also incorporates a carry handle and a protective sleeve for the titration vessel and electrodes. The unique low drift cell glassware design is by far the easiest to use and also the most robust. The electrode locking system allows the joints to seal completely, without the use of grease or PTFE sleeves, and provides improved baseline stability. Hassle free assembly and disassembly. This glassware enables users to transport the instrument with reagents already in the titration cell so that it can be used immediately on arrival.
