Descriptions

The HI-902C1-02 is an automatic titrator that complements our wide range of products dedicated to quick and accurate laboratory analysis. HI-902C1-02 can perform acid/base, potentiometric, ORP, complexometric, precipitation, back titrations and titre determinations.

The HI-902C1-02 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 colour 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 optimised. 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-902C1-02, as well as create a complete workstation with a PC, monitor, keyboard and printer.

The HI-902C1-02 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.
