Automatic Titration Systems
- Quick & Accurate Analysis
- A Complete Workstation
- All Information Displayed on Graphic LCD
HI 901 and HI 902 are the new automatic titrators from HANNA instruments® to enhance the wide range of products dedicated to quick and accurate laboratory analysis. Each is provided with many features for routine titrations. HI 901 and HI 902 perform acid-base, potentiometric and amperometric titrations. The versatile HI 901 and HI 902 offer a total of 100 methods: 89 of these can be customized. When turned on, the instruments run an accurate unit check and they are ready for the first titration of the day. The display shows the chosen method, correlated information, and also shows the controls for possible parameter adjustment, and quick and simple burette maintenance. The titration curve is shown on the large display; this feature is useful when new methods are tested or when a procedure needs to be optimized. At the end of the titration, all data, including the graph, are automatically stored in the memory and can be downloaded through the instrument’s floppy drive. Burette maintenance is very simple and completely automatic: the user can decide to purge it or to wash it and can select how many washings to perform. Thanks to the new Clip Locktm system for burette replacement, changing from one titrant to another will be very easy! Both HI 901 and HI 902 can drive two pumps, but HI 902 is a more advanced system. In fact, while HI 901 can drive the two pumps separately, HI 902 can drive them concurrently and then perform back titrations. Finally, HI 902 can perform more complex titrations, thanks to the possibility to determine more than one equivalent point.
HI 901 and HI 902 are supplied complete with dosing pump, 25 mL burette, aspiration and dosing tubes, sliding positioning collar, temperature sensor, burette assembly key, start-up and PC connection software, RS232 PC connection cable, power supply cable, instruction manual and quality certificate. HI 902 is also supplied with software for back titration and for titrations with several end-points.
