AT1000 Potentiometric Titrator with 1 Burette – Model AT1102

Simply add your sample, press the button and read your titration results

The AT1102 model is an accurate, reliable and easy to use instrument for performing titrations in the laboratory. This titrator was designed in Germany as part of the Hach Titralab® AT1000 family of automatic titrators and includes one burette and two measurement inputs. The titrator is delivered preassembled for easy installation and does not require complex programming like other titration systems on the market. This system offers superb dependability so you don’t suffer from downtime and it is easy to use for all skill levels, reducing operator training and process time. In fact, with an autotitrator the operator will be able to begin preparing the next sample while the instrument is performing the current measurement, thus improving lab throughput. More importantly however, the automatic titrator eliminates manual processes and operator interpretation, significantly improving accuracy and reliability so you can trust your measurements from day to day. If you perform any of the titrations listed in the Application Packs section below this is the instrument for you!

Application Packs

The AT1102 instrument can be used with the following Hach Application Packs:

- pH & Alkalinity in Water (Hach p/n AP0001.AT1102)

- pH/Alkalinity & Conductivity (Hach p/n AP0002.AT1102)

- FOS/TAC - Volatile Acids & Alkalinity in Biogas (Hach p/n AP0006.AT1102)

- pH & Total Acidity in Wine & Juices (Hach p/n AP0008.AT1102)

- TAN (Hach p/n AP0015.AT1102)

- TBN (Hach p/n AP0016.AT1102)

- BR₂/I₂ Number (Hach p/n AP0018.AT1102)

Each application pack includes a pre-programmed application that runs on the instrument as well as a set of accessories necessary to perform your titrations. Please review the specific webpage for each application pack for further details, and we suggest selecting your Application Pack before your instrument. If you haven’t found the application pack that meets your needs on this page please enter “AT1000 Application Pack” in the search field, hit enter and then click on the “PRODUCT FAMILY: AT1000 Application Packs” to see the full list of Hach’s AT1000 Application Packs.

Ordering Information

A base titration system consists of an Application Pack and an Instrument, so please make sure you add the Application Pack you’ve chosen and the Instrument (in this case Hach p/n AT1102) to your Hach order. In addition, make sure you added the reagents required to perform your titration measurements when selecting your Application Pack. If you did not do this yet, navigate to the Application Pack website, review the method found under the “Parameter/Reagent” tab for a list of reagents and then select what you need from the “Consumables” tab. If you have any questions about the instrument, the application packs or the reagents after reviewing our website content please contact Hach Technical support. We have a great team of experts who can quickly and painlessly guide you through the process.
