Powerful Customization, Accurate Analysis

HI 901 and HI902 are automatic titratorsfrom

HANNA

that compliment our widerange of products dedicated to quick and accurate laboratory analysis. HI 902 also features the addition of back-titrationcapabilities. Each unit is provided with a host ofnumerous features suitable for routinesample analysis. HI 901 and HI902perform acid/base, potentiometric and amperometric titrations. These versatile titrators support up to10,000 methods: standard or user defined. When powered on, the instrument initiates an internal diagnostics check and then readies itself for the first titration of the day. A large LCD screen clearly shows the chosen method, correlated information and also indicates which parameters may be adjusted. A real-time titration curve is shown on the 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 memory and can be copied to disk via the built-in floppy drive or through direct connection with the serial cable supplied with the titrator. The titrators are equipped with an RS485 serial port.Burette maintenance is simple andcompletely automated. The user can decide to purge it or wash it and can select how many washings to perform. With our exclusive Clip Lock™ system forburette replacement, changing from one titrant to another is done in a flash! Often, preliminary titration operations are very long and arduous. A burette oftenneeds to be adjusted for correct dosing, which extends waiting time for new sample analysis.

HANNA

has engineered away to solve this problem.The innovative Clip Lock™ system allowsusers to change burettes in two simple steps, passing from one titrant to the next without any problem. Additionally, HI 901and HI902 automatically recognizes the volume of the new burette. Both HI 901 and HI 902 can drive twopumps, with the HI 902 incorporating a more advanced system. While the HI 901 can drive the two pumps separately, HI 902 can also drive them concurrently and perform back titrations. HI 902 can perform more complex functions with the ability to determine more than one equivalence point.Users can connect pH or ORP electrodes tothis unit, as well as create a complete workstation with a PC, monitor, keyboard and printer. This unit complies with GLP specifications, providing validation support for analysis. All GLP information from each sample can be stored, including ID number, date and time of analysis, electrode ID code and last calibration date. Up to 100 reports of analysis, completewith titration curve graphing is possible. A calibration "time-out" can be set and the user can be advised when the pH electrode needs to be calibrated. The instrument's status can be viewed clearly on the large LCD screen. Contained in the set-up menu, features like language, displaybrightness, resolution, pH electrodecalibration, date and hour can be adjusted. During analysis, the titration is displayed in real-time together with the stored data. Date, hour, temperature (when probe is connected) and warning messages such as a pH electrode calibration message can all be displayed for your convenience.

Automatic Burette Volume Recognition

This feature makes exchanging titrants convenient, safe and fast.

Stirrer

The optional stirrer ensures an effective mixing with a selectable speed from 100 to 2500 rpm.

Quick Change

Keep several burretes on hand for a quick change.
