NOTHING HELPS TITRATIONS LIKE FISHER'S NEW
CAT Fisher's Computer-Aided Titrimeter* combines enormous analytical capability with astonishing simplicity of operation. It performs titrations to fixed endpoint targets, titrations with derivative detection of equivalence points, computational methods such as equilibrium and incremental titrations, as well as direct potentiometry in pH, mV, or activity with ion-selective electrodes. Handles all calculations automatically to provide results in your preferred units. It makes things simple. Six-digit display verifies keyboard entries, shows answers. Easy-to-understand messages on 20-character display lead you step-by-step through memory-stored methods, or through simple keyboard setup and storage of your own customized methods, for use when needed. Just touch the HELP key if you want more detailed instructions — you get a printed explanation immediately! The Printer/Plotter produces curves and/or printouts of analytical results, with documentation. The Computer-Aided Titrimeter keeps track of information you need. Methods. Electrode characteristics. Sample data. Stores stacked sample weights fed directly from an accessory balance or keyed-in, and lets you edit the values. Volatile memory is battery-protected. System handles single samples or up to 32 per load. Titration rate control is automatic. So are electrode standardization and electrode efficiency computation. Digital buret is microprocessor-controlled and has quick-change syringe assembly. System is modular. You can add on easily as your needs grow. The superiority of our new CAT reaffirms Fisher's continued dedication to excellence in the field of titration. We have been designing and manufacturing our own titration equipment for over 40 years. Complete backup support is as close as your Fisher branch. For brochure, circle reply card number or phone us at (412) 562-8543.
