Tính năng kỹ thuật:
-
The SAT-500 salt / chloride
analyzer is designed to measure the concentration of salt and chloride ions
quickly and easily in all types of products and where low level chloride
measurement is required. It is an extremely helpful tool in the busy QA/QC lab
or where high accuracy and quick analysis time is required.
-
Typical measurement time is
under 30 seconds.
-
Extremely accurate.
-
Absolute method. No silver
nitrate reagent is used. titrant standardization is not necessary.
-
Simply dispense the sample
with a pipette into the measuring cell. Measurement begins automatically.
-
Built in printer
-
Direct concentration
displayed on instrument display.
-
Data memory for 300 results
-
Optional PC software is
available for spreadsheet data control/archive
-
Dilution ration and sample
size are settable

Measuring Principle:
§ The
SAT-500 is a dedicated coulometric titrator for chloride. Silver is stripped
from the cathode, a pure silver wire, via an electrical current. By
incorporating Coulombs law, very low levels of silver can be generated which in
turn complex with the chloride in solution from the sample. The solution
potential is monitored with a silver wire and reference electrode sensing
system to determine the end point of the reaction, the point at which all the
chloride ions have complexed with silver, forming a silver chloride
precipitate.
§ The
instrument calculates the concentration and the results are automatically
displayed and printed out in %(w/v), %(w/w), mg/l, or mol/l as NaCl or Cl
(selectable).
