Automatic Potentiometric (pH/mV) Titration System - HI901

A Better Titration Experience

Our friendly technical consultants take pride in helping make your titrator selection easy – every step of the way. From determining materials and methods to installation and beyond.

The HI901 is an automatic titrator that brings together our wide range of products dedicated to efficient and accurate laboratory analysis. This titration system is provided with a host of numerous features suitable for routine sample analysis and performs acid/base, potentiometric and amperometric titrations. This powerful titrator dispenses the titrant, detects the endpoint, and performs all necessary calculations and graphing. In addition to titration mode, the HI901 can also operate as an independent pH, mV and temperature meter.

Titrator Capabilities

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 Titration Types

Paired with the right electrode, our potentiometric titrator can perform acid/base, redox (ORP), complexometric, precipitation, non-aqueous, and argentometric titrations.

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 HI901 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 precise 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.

Interface & Display

Large Interactive Display

A large black and white 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

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 and procedures.

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, and calibration information. Reminders for titrant age and standardization expiration can be set.

Effortless Data Transfer

User customized reports can be printed or transferred directly to PC via RS232 interface.

Connectivity & Functionality

Multifunctional

The HI901 functions as a titrator, but can also be used for precise pH, mV and temperature measurements. Valuable laboratory bench space is saved, and multiple analyses can be performed on one sample.

Multiple Peripherals

Users can print reports directly from the titrator using a standard parallel printer. An external monitor and keyboard may be attached for added versatility, as well as an analytical balance for automatic sample mass entry for titrations.

Methods of Analysis

Customizable Methods

The HI901 can store up to 100 user-defined or standard titration methods for ultimate flexibility. Each method may be customized and optimized for performance based on application and user requirements.

Titration Method Support

Onsite installation, training, and customization is available from one of our Applications or Service experts. Hanna offers continued support via phone or webinar for any questions you might have along the way.

Market Specific Methods Packs

Hanna offers titration method packages for various markets including food, beverage, dairy, wine, and more. Ask our Sales Consultants about which methods in our library are available for your specific needs.

Adaptable Standard Methods

Our technical experts can program and customize standard methods developed by such affiliations as ISO, ASTM, AOAC, AOCS, EPA, and more directly onto your titrator. Ask our Sales Consultants which standard methods are possible with our HI901 system.
