Description
Technical Description – TurBiScat
The measurement of turbidity in the brewing industry and specifically the monitoring of filtration in the brewing process is firmly connected with the name SIGRIST. SIGRIST offers a full range of optical measuring instruments covering all important applications in breweries – right from the brew house through to the laboratory.
Monitoring wort turbidity at the lauter tun and at the mash filter Due to variation in quality of the raw materials, it is important to obtain information on the quality of the wort at an early stage. It makes sense to carry out this monitoring with a forward scatter angle photometer, i.e. the TurBiScat 25° (recommendation EBC/MEBAK) or a dual-angle measurement with the TurBiScat 90/25. If rising turbidity values are seen quickly, a process adjustment can then be carried out at the mash stage. During the subsequent brewing process, measures can be taken in advance to filter the problematic brew.

Sigrist Communication Software
Vx29 is the current software controlling communication between the analyser and the SICON.
Check for updates periodically. Sign up to our newsletter for notifications of software updates.
The control unit SICON uses state-of-the-art touch screen technology with colour display. It allows simple operation using logical menu guidance. The user can select how results are displayed, either as plain values, graphs or historical data, including the indication of system and alarm status.
The control unit SICON offers all possibilities of full system integration using various interface options. A SD card is standard and can be used for data logging with almost unlimited storage capacity.
The SICON is available as a control unit for a single instrument, or the SICON M Control Unit which allows simple operation of several instruments up to a maximum of 8 measuring channels.
