INTRODUCTION
1 INTRODUCTION
HI 901 and HI 902 are automatic titrators with high accuracy, great flexibility and repeatability.
The titrators are designed to perform a variety of potentiometric titrations, allowing the user
to obtain both good results and high speed analysis.
The main attributes of these titrators are:
Flexibility Support up to 100 titration methods (standard and user defined).
High accuracy Precise dosing system (under 0.1% accuracy).
Precise mV and pH measurements (± 0.1 mV and ± 0.001 pH accuracy).
Interpolated end point volume.
Repeatability Powerful built-in algorithms for equivalence point detection (first derivative and second
derivative detection algorithms, filtered derivatives option, settable range for equivalence
point detection).
Fixed end point mV or pH.
Quick results Standard titration methods.
Pre-titration dosing feature.
Dynamic / Linear dosing feature.
Complete report The results are displayed directly in the selected units.
Titration graph can be displayed on line and saved.
User customized reports can be printed, saved on floppy disk or transferred to PC via
RS232 interface.
The sample information and data stamp are included in the report.
Direct measurements The titrator can also be used for precise mV, pH and temperature measurements.
Report of data logging is available for direct measurements.
GLP features Up to 5 standardization points for the pH electrode.
Reminders for titrant age and standardization expiration.
Fields for specific annotations.
Large graphical display 7.5” B/W graphical display with backlight.
Easy to view text and graphs.
Lots of information on each screen.
Self diagnosis and Integrated help is available.
