Full Description Specification

HI-901C1 can perform acid/base, redox (ORP) complexometric, precipitation, non-aqueous, argentometric and ion selective titrations.

  • For a full demonstration, call today on 01525 850855 to make an appointment with one of our titration experts.

This powerful titrator dispenses the titrant, detects the endpoint, and performs all necessary calculations and graphing automatically. In addition to titration mode, the HI-901C also operates as a fully functional pH, mV/ORP, and ion selective electrode (ISE) meter.

This titrator is supplied with a pack of standard methods or you can create your own. Methods (standard or user) can be easily transferred between titrators via USB flash drive or PC application.

Burette and dosing system

Exchangable 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 HI-901C comes standard with a 25ml burette but may be equipped with a 5ml, 10ml or 50ml burette. Each burette is constructed with a ground glass syringe and chemically resistant PTFE plunger.

Linear and Dynamic Dosing

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 made of durable, chemically resistant PTFE and feature a light-blocking polyurethane outer sleeve to protect light sensitive reagents.

Methods of analysis

Customisable Methods - The HI-901C can store up to 100 user-defined or standard titration methods. Each method may be customised and optimised for performance based on application and user requirements.

Titration method support - Onsite installation, training, and customisation is available from our titration experts. Hanna offers continued support via phone or email 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 product specialists about which methods would be best for you.

Adaptable standard methods - Ask our product specialists which standard methods are possible with the HI-901 system.

Connectivity and Functionality

Multi-functional with four working modes - The HI-901C 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 burettes and two analogue boards, which allows two electrodes and two stirrers to be simultaneously connected to one unit.

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 titrators.

About versatile data management

HI-901 titration system can be easily incorporated into any existing GLP data management programme.

  • Easily record all necessary GLP information with every sample, such as sample identification, company and operator name, date, time, electrode ID codes and calibration information.
  • Data can be transferred to a PC using Hanna HI-900PC software
  • The USB port allows for the easy transfer of methods, reports and software upgrades via USB flash drive
  • 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

PC Interface - Download test results to a computer programmed with HANNA’s Windows® compatible software directly from equipment via a USB port or a RS232 cable outlet.
