Powerful Customization, Accurate Analysis
The HI 902C is an automatic titrator that complements our wide range of products dedicated to quick and accurate laboratory analysis. HI 902C can perform acid/base, potentiometric, ORP, complexometric, precipitation, back titrations and titre determinations.
The HI 902C dispenses the titrant, detects the endpoint and performs all necessary calculations automatically.
This versatile titrator supports up to 100 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 color LCD screen clearly shows the chosen method and related information. A real-time titration curve can be 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 via the built-in USB drive or through direct connection with a PC.
This titrator is supplied with a pack of standard methods or you can create your own. Methods (standard and user) can be upgraded, stored or deleted by connecting the titrator to a PC with HANNA software or USB flash drive. Software updates can also be performed using a USB flash drive.
Users can connect pH, ORP or ISE electrodes to the HI 902C, as well as create a complete workstation with a PC, monitor, keyboard and printer.
The HI 902C complies with GLP specifications. All GLP information from each sample can be stored, including ID number, date and time of analysis, electrode ID code, and last calibration date.
Clip-Lock™ Exchangeable Burette System
With Clip-Lock™, it only takes a few seconds to exchange the reagent burettes to perform a different titration.
The Clip-Lock™ exchangeable burette system prevents cross contamination while reducing loss of time and reagents. Burettes simply slide out for quick exchanges and detaching the aspiration and dispensing tubes from the titrant bottles is easy.
Interrupting an important cycle of analysis due to a malfunctioning burette is a thing of the past. With the HANNA Clip-Lock™ system you can simply substitute the burette and complete all your tests with the same titrant!
Having several prepared burettes on hand will make the HANNA HI 902C one of the fastest and most versatile titration systems on the market.
