Enhanced Security Options
Administrative users can set a PIN code on the device protecting against unauthorized access. Titration method options and results are tamper-proof while a non-administrator operates the titrator, ensur+I487ing records remain safe, secure, and traceable.
Dynamic Titrant Dosing
The dynamic dosing feature allows for timely and accurate titration results by relating the titrant volume dosed to the mV response from the titration reaction. This provides for larger doses near the beginning of a titration and smaller, more precise doses near the titration endpoint.
Signal Stability Timing
The signal stability feature monitors when the mV response of the titration reaction stabilizes before providing the next titrant dose. This ensures reliable measurement values throughout the length of a titration.
Equivalence Endpoint Detection
Equivalence endpoint detection is critical in applications where fixed endpoints are not specified in standard methods. This endpoint indicates where the mV response from the titration is greatest with respect to the volume of titrant dosed.
Multiple Equivalence Point Detection
The HI902C can detect multiple equivalence points during one titration as specified and required in certain standard methods and applications.
Method Sequencing
The HI902C offers users the option of linking two methods. This allows for two analyses to be run on the same sample including direct measurements, single endpoint titrations, multiple equivalence point titrations, and back titrations.
Multiple Titration Types
Paired with the right electrode from our sensor line, our potentiometric titrator can perform acid/base, redox (ORP), complexometric, precipitation, non-aqueous, argentometric, and ion selective titrations, as well as back titrations and titre determinations.
Direct Measurement Functionality
The HI902C performs as a high accuracy pH, ORP, and ion selective meter that can link, log, and report direct measurements. Users can easily track and manage data without the hassle of manual record keeping.
Burettes & Dosing System
Exchangeable Burette System
With Hanna’s Clip-Lock™ burette feature, it only takes a few seconds to exchange titrants and reagents preventing cross-contamination and saving time.
Multiple Burette Sizes
The HI902C comes standard with a 25 mL burette but may be equipped with a 5 mL, 10 mL, or 50 mL burette. Each burette is constructed with a ground glass syringe and chemically resistant PTFE plunger.
Precision Dosing Pump
Our unmatched 40, 000 step piston driven pump is capable of dosing extremely small and highly accurate volumes of titrant or reagent.
Chemically Resistant Tubing
Aspiration and dispensing tubes are constructed of durable, chemically resistant PTFE and feature a light-blocking polyurethane outer sleeve to protect light sensitive reagents.
Automatic Reagent Addition
A second burette may be programmed to volumetrically dispense reagent prior to titration or direct measurement. This helps achieve consistent and accurate results and prevents operator errors such as incorrect volumes or forgetting reagent addition.
Interface & Display
Interactive Color Display
A large, color LCD screen clearly shows the chosen titration method along with results, units, titration volume, temperature, and mV or pH values.
Detailed Titration Graphs
A real-time titration curve can be displayed during each titration; this feature is useful when new methods are tested or when a procedure requires optimization.
Simple & Quick Navigation
Virtual key selections present on the display allow for simple and quick navigation between screens and menus without getting lost in a nest of information.
Data & Storage
I1740
Customizable Analysis Reports
Each analysis report is fully customizable so users can ensure they are storing and filing the appropriate data required for their application.
Flexible GLP Management
All necessary GLP (Good Laboratory Practice) information can be recorded with each sample including: sample identification, company and operator name, date, time, electrode ID codes, and calibration information.
Effortless Data Transfer
Data can easily be transferred to a USB flash drive or PC with the Hanna HI900PC application software. The conveniently located port allows for the transfer of titration methods, titration reports, and software upgrades via USB flash drive.
Connectivity & Functionality
Autosampler Connectivity
The HI902C works seamlessly with our HI921 Autosampler featuring 16 or 18 sample tray options, automatic tray identification, and automatic beaker detection. Up to three peristaltic pumps for reagent addition and removal can be connected and real-time analysis and sequencing progress is visible on the HI902C display as well as indicated by the LED lights of the Autosampler.
Multifunctional
HI902C functions as a titrator, pH meter, mV/ORP meter, and ISE meter. Valuable laboratory bench space is saved, and multiple analyses can be performed on one sample.
Multiple Connections
The titrator offers device support for two analog boards, allowing up to two electrodes, two burettes, and two stirrers to be connected to one unit simultaneously.
Multiple Peripherals
Users can print reports directly from the titrator using a parallel port interface. An external monitor and keyboard may be attached for added versatility, as well as an analytical balance for automatic sample mass entry for titrations.
