Automatic Potentiometric (pH/mV/ISE) Titration System

fisher brand

The HI902C is an automatic titrator that complements our wide range of products dedicated to efficient and accurate laboratory analysis. The HI902C 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. This powerful titrator automatically dispenses the titrant, detects the endpoint, and performs all necessary calculations and graphing. In addition to titration, the HI902C also operates as a fully functional pH, mV/ORP, and ion selective electrode (ISE) meter.

Titration Maintenance Agreement

You’ve made a great choice when you go with Hanna for your titration needs. All it needs is a little TLC, and it will serve you well for years.

All titration equipment requires annual maintenance due to the wearable parts and the harsh chemicals, such as sodium hydroxide, required in many titrations. An annual checkup, calibration, and replacement of burette accessories result in a long instrument life, accurate and precise results, and safe operation.

As always, Hanna delivers the quality and expertise you need at an affordable price. The Hanna Titration Maintenance Agreement keeps your instrument in optimal working order and ensures that you stay up-to-date on best testing practices. The agreement includes the following services and perks, which keeps your instrument performing at its best:

  1. One (1) onsite calibration, performed for you by certified personnel
  2. One (1) time replacement of wearable parts
  3. Backup of your titration methods
  4. Coverage by the Hanna Loaner Program. When you send your titrator in for service or repair, we will give you one of ours to borrow, with your methods loaded, so that you’ll never be without.
  5. One (1) refresher training by a Hanna expert
  6. 25% off all services, including your install
  7. 5% off all Hanna purchases
  8. Certificate provided to you upon completion

The Hanna titration line enjoys an incredibly low cost of ownership, and the Titration Maintenance Agreement is the cornerstone of that value.

Description

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, ensuring 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.

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.

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.

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.

Methods of Analysis

Customizable Methods

The HI902C can store up to 100 user-defined or standard titration and direct measurement methods. Each method may be modified 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 for any questions you might have along the way.
