GENERAL DESCRIPTION
If protein instability is detected, a next test can help defining the right amount of bentonite to be
added for improving protein stability. It is important not to overdose bentonite, avoiding stripping
wine flavour, body, and significant loss of color, especially in young red wines. Moreover, adding only
the necessary amount of bentonite to obtain the desired protein stability is also costs saving.
2.2. TAG IDENTIFICATION SYSTEM
Hanna is the first manufacturer of turbidity instruments that has decided to add the unique T.I.S. - Tag
Identification System to portable turbidity meters, to meet the more restrictive needs for traceability
and data management of our clients.
The system is designed for scientific and industrial applications, or to prove during safety audits and
inspections that samples have been truly taken on pre-established locations.
The system is as easy to install as to operate. Just fix the so-called iButton® tags near your sampling
sites that need to be checked often, and with this the T.I.S. is setup. The tag contains a computer chip
embedded in a durable stainless steel can. It is designed to withstand the harsh environments, indoors
or outdoors. The number of tags that can be installed is practically unlimited, because each tag has
a unique identification code.
Immediately after installation of the tags you can start collecting data. Use the meter to take
measurements and memorize the test result by pressing the Log-on-Demand key. Then, the instrument
will ask for the tag identification. Simply touching the iButton® with the matching connector on the
meter does identify and authenticate logging, by storing the iButton® serial number, time and date
stamp events.
The power of the T.I.S. features resides in the PC application. Download all test data to your PC and
use our HI92000 Windows® compatible application software for further data management. You can
sort or filter all your collected data on different criteria like on a specific sampling location, parameter,
date and time intervals, or fix range to filter measured values. The data can be plotted in a graph,
exported to other common Windows® applications or printed for reporting purpose.
It is also possible to add new tags later on, thus increasing an already existing database. Each
time the PC software recognizes a not already registered tag, it will ask for a description of the new
sampling location.
