Biogas Titrator for FOS/TAC analyses


Biogas Titrator for FOS/TAC analyses
Product #: R41T114


Reliable Assessment of the Fermentation Process

Process control for biogas fermenters is crucial in order to immediately detect any disruption in the digestion process. With the Biogas Titration Manager from Hach, you can be sure your plant is achieving reliable and efficient biogas production. The Titration Manager comes complete with a dedicated FOS-TAC (volatile organic acid and buffer capacity ratio) application package so you are ready to get started right away. All you need to supply is the sample!

Intelligent Design Ensures Effortless Setup and Maintenance

Electrodes and tubing slot secure in place with one easy movement thanks to our unique bayonet concept. For convenient installation and maintenance, the mono-block titrating burette is mounted in no time.

Intuitive Interface Guides You at Every Step

Titration Manager prompts you with clear-text messages in a choice of languages, making it much easier when you're doing routine work. The titration curve is easy to follow live on the large graphic display together with electrode and titrant status.

One-touch Selections and Preprogrammed Functions Make Titrations Easy to Run

Interface gives instant access to routine functions, making it by far the simplest titrator of its generation. Preset routines guide you when running analyses, repeating measurements and performing maintenance. Titrator allows you to automatically sequence and repeat measurements--ideal for direct measurement followed by a titration. Predefined electrode and reagent libraries mean you save time and effort setting up your application.

High-Resolution Burette, Unique Addition Technique and Special Algorithms Ensure Accurate Results

Integrated titrating burettes offer the highest resolution on the market giving unbeatable accuracy for your potentiometric titrations. Innovative electronic design supporting effective PID regulation loop algorithms combined with incremental or dynamic continuous titrant addition modes allow you to reach end points or to determine inflection points even more quickly. Whether you are working with sharp or weak curves or running single or multiple IP, detection is fast and reliable.
