67-6819-91　Nitrite Ion Meter　TiN-9003

คุณลักษณะ

The TOKO Handy Nitrite Ion Meter is a diaphragm electrode meter dedicated to measuring nitrite ion.
When the pH of the sample drops below 1.5, nitrite turns into nitrite.
Nitrous acid passes through the membrane and enters the electrode, changing the pH of the electrolyte according to the concentration of nitrous acid.
The diaphragm-type nitrite ion electrode measures this pH change to detect nitrite ion concentration.
You can also measure nitrate ion by the copper-cadmium column reduction method.
Dongxing Chemical Laboratories, which has been developing pH electrodes for many years, has developed a new chip-type small sensor that enables faster and more stable measurement of nitrite ions by simply dropping a pH regulator onto a sample.
Up to 1000 data can be memorized and data can be automatically collected using interval measurement.
