In the current industrial environment, the content of oxygen plays an important role in industrial production, so it is often measured. There are various products on the instrument market, but in terms of measurement principles, there are mainly 2 measurement methods: (1) Thermal magnetic oxygen analyzer The principle is to use the physical characteristics of […]
Water Dissolved Oxygen Analyzer is a polarographic analysis instrument designed for ppb level dissolved oxygen measurement such as boiler feed water and condensate water. Ensure the stability and accuracy at low concentrations, and greatly improve the measurement performance and use environment. Dissolved oxygen meter is mainly used for continuous monitoring of dissolved oxygen value in […]
Dissolved oxygen analyzer measurement principle: the solubility of oxygen in water depends on temperature, pressure and dissolved salts in water. The sensing part of the dissolved oxygen analyzer is composed of gold electrode (cathode) and silver electrode (anode) and potassium chloride or potassium hydroxide electrolyte. Oxygen diffuses through the membrane into the electrolyte and the […]
The paramagnetic oxygen analyzer is designed based on the high paramagnetic characteristics of oxygen. The instrument adopts the principle of magnetic mechanical, with high detection accuracy and long life. At the same time, it has a variety of non-explosion-proof and explosion-proof models, which can be used in various safety conditions. Industrial applications. Detection principle: The […]
The online trace oxygen analyzer is a chemical battery, which is mainly composed of a cathode, an anode and an electrolyte. The above components are sealed in an inert shell. The oxygen in the measured gas enters the O2 near the cathode in the battery to obtain electrons. The anode is made of lead metal. […]
It is well known that there are many detection principles of oxygen analyzers. The common ones are electrochemical oxygen analyzer, paramagnetic oxygen analyzer, zirconia oxygen analyzer, laser oxygen analyzer, etc., oxygen analyzers of each principle have different advantages And disadvantages, this time Aiyi Technology will introduce the advantages of electrochemical oxygen analyzer and other principles […]
Trace oxygen analyzer is divided into two analysis principles: fuel cell method trace oxygen analyzer and zirconia trace oxygen analyzer. The following editor will tell you some precautions. Trace oxygen analyzer supporting pipeline Sealing should be ensured. Small leaks will diffuse the oxygen in the ambient air, which will make the measured value higher. Although […]

Magnetic oxygen analyzer and magnetic mechanical oxygen analyzer (1) Detection principle of thermomagnetic oxygen analyzer. The detector is placed in a constant temperature chamber higher than the ambient temperature. The detector is equipped with a constant magnetic field. When the sample gas to be detected flows through the detection chamber of the detector, the magnetic […]
The principle of trace oxygen analyzer mainly includes chemical cell method, primary cell method, fuel cell method, Hertz cell method and concentration cell method. When performing trace oxygen analysis, since the oxygen content in the air is as high as 21%, it is easy to cause contamination and disturbance to the sample if it is […]
