KNA500 Nitrate Ion Analyzer PVC Sensor For Fishery Industry
Product Introduction
Nitrate ion analyzer mainly uses ion selective electrode
measurement method to achieve accurate detection
Of. The electrode has an ion selective membrane that reacts with
the corresponding ion in the sample under test. The membrane is
An ion exchanger, which reacts with the ionic charge to change the
membrane potential, can detect the liquid, like
The electric potential between this and the membrane. The
difference between the two potentials detected on both sides of the
membrane will generate an electric current
The test electrode, the reference electrode liquid forms the "loop"
on one side, the membrane, the internal electrode liquid, and the
internal electrode on the other
Edge.
The difference in ion concentration between the internal electrode
liquid and the sample will produce electrochemical reactions on
both sides of the membrane of the working electrode
The voltage is directed to the amplifier through a highly
conductive internal electrode, as is the reference electrode
To the location of the amplifier. Determination is obtained by
detecting an exact standard solution with a known ion concentration
To measure the ion concentration in the sample.
Occurs in the aquifer of the ion-selective electrode substrate when
the measured ion contacts the electrode in solution
Ion migration. The charge change of the migrating ion has an
electric potential, which causes the potential between membrane
surfaces to arise
Produces a potential difference between the measuring electrode and
the reference electrode.
Areas of use include food, drinking water, agriculture and so on.

NTU
The unit of turbidity is "degree", which is equivalent to the
degree of turbidity produced by 1L water containing 1mg SiO2 (or
white clay, diatomite), which is 1 degree, or Jackson.Turbidity
unit is JTU, 1JTU=1mg/L white clay suspension.
The turbidity shown by modern instruments is the unit of scattering
turbidity NTU, also known as TU.1NTU= 1JTU.
Recently, it is considered internationally that the standard of
turbidity prepared with ullotropin-hydrazine sulfate has good
reproducibility and is chosen as the uniform standard of
FTU.1FTU=1JTU.
