Hi, I am Businessman I found this sample from https://www.indotrade.co and think it might be useful to you. ------------------------------------------------------- HANNA, HI 902C New Multiparameter Titration System with Color LCD The HI 902C is a automatic titrator that also features back-titration capabilities and multiple equivalence points. The titrator can perform acid/ base, potentiometric, ORP, complexometric or precipitation titrations. This versatile titrator can support 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 correlated 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. Users can connect pH, ORP or ISE electrodes to this unit, as well as create a complete workstation with a PC, monitor, keyboard and printer. This unit 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. The HI 902C dispenses the titrant, detects the endpoint and performs all necessary calculations automatically. This titrator is supplied with a pack of standard methods or you can create your own. Using a USB flash drive or connecting the titrator to the HI 900 PC application, methods ( standard and user) can be upgraded, stored or deleted. FEATURES: • Large 7.5” ( 320 x 240 pixel) color LCD with backlight • Intuitive user interface • USB port for PC connectivity, software upgrades and data file transfers via USB flash drive • Four working modes; potentiometric titrator, pH meter, mV meter, and ISE meter • Potentiometric titrator • HI 901/ 902 can be used for acid/ base, non aqueous, ORP, complexation, and precipitation titrations • Support up to 100 titration methods ( standard and user defined) • The titrator is supplied with a pack of standard methods or you can create your own • Titration graph can be displayed on-screen and saved • Choice of end point detection; Equivalence point ( 1st or 2nd Derivative) or fixed pH/ mV value • Reminders for titrant age and standardization expiration • Multiple End Point and Back Titrations ( HI 902 only) • Two sensor inputs with the addition of a second analog board • Precision Titrant Delivery System • 40, 000 step, screw-drive, piston pump • Precision ground, 25 mL glass burette with PTFE plunger, PTFE burette tubing, and polyurethane tube jacketing • Clip-Lock exchangeable burette system enables users to exchange burettes in a matter of seconds • pH meter • Full featured research grade pH meter • Automatic Temperature Compensation ( ATC) • Up to 5 calibration points with automatic buffer recognition of standard buffers • Up to 5 custom buffers can be used for calibration • mV ( ORP) meter • Relative mV Calibration • ISE meter • Numerous concentration units including; mol/ L, mmol/ L, mg/ L, mg/ mL, ug/ L, % , ppt, ppm, g/ L, and user defined • Up to 5 calibration points with 5 custom standards VERSATILE DATA MANAGEMENT • HI 900 Series titration systems can be easily incorporated into any existing GLP data management program: ( Users can easily record all necessary GLP information with every sample including sample identification, company and operator name, date, time, electrode ID codes and calibration information.) • Data can also be transferred using the USB port for communication with a PC. • All test results can be transferred directly to a PC. • Users can print reports of analyses directly from the titrator using a standard parallel printer. • An external monitor and keyboard can be attached for added versatility.
