Meat / Grain Kjeldahl Nitrogen Analyzer 7" LCD Touch Screen Siemens
PLC Control System
Brief introduction of kjeldahl protein analyzers :
The working principle of 9870 auto Kjeldahl analyzer is based on
the classical methods, it's namely the "color method" developed
auto Kjeldahl analysis system. It is consistent with national and
international standards and methods of Kjeldahl nitrogen. It's a
high-performance instrument due to the concept of its design and
application of new technologies, therefore, its comprehensive
technical performance and very competitive price even much better
than the similar products which the oversea competitors standing
behind; thus, it becomes a very reasonable and logical choice to
the Chinese local users as an outstanding import substitution.
Features of kjeldahl protein analyzer:
Ø Addition of reagents, distillation, titration, analysis and
calculation, record (data) storage, waste discharge, all the
above-mentioned program can be accomplished by simply click on ONE
BUTTON.
Ø Display. 7-inch color touch screen, bilingal operating system
(English & Chinese), interactive mode of operation.
Ø Titration curve display. Real-time observation, analysis to the
titration process to see whether it's successful or fail and figure
out the reason through curve. It's also able to analyze and
determine whether the choice of titration is correct through the
curve.
Ø High-integrated modular structure. Patented technology of
"modular construction" is composed of steam section, titration
section, control section, and crate section; therefore, the
structure ensures reliable operation and easy maintenance.
Ø Titration cup exposed structure. It's convenient for users to
observe and take out cup for cleaning.
Ø The whole system. The system adopts the CPC company (US) fast for
fluid pipe, to ensure that the system not leakage and prolong the
life of equipment. The unique color label and color ring system
which is able to help user avoid twisting and wrong operation.
Ø Patented technology. Siemens PLC Board technology applied
enabling to protect the running reliability and stability
completely.
Ø Different pipes perform its own function. Steam, waste water
adopts fluoride pipeline; the liquid portion selects the modified
silica gel pipeline (which is made in USA) changing tube aging
caused by the leakage, leakage of steam corrosion problems.
Ø Pre-warming function. The instrument itself is able to pre-heat
automatically, and keep the certain temperature as preset, prior to
use; therefore, it may save time and energy for user.
Ø Fertilizer (nitro) analysis mode. Addition of fertilizer analysis
capability achieves multi-purpose instrument which may save
considerable cost for user.
Ø Multi-alkali adding technology. In the operation process,
multi-alkali adding technology solves the problem of halfway quit
in the analysis process which is due to shortage of alkali adding.
