Advantages: It has advantages in measuring trace oxygen. Basic principle: The fuel cell oxygen sensor is composed of a highly active oxygen electrode and a lead electrode, and is immersed in the KOH solution. Oxygen is reduced to hydroxide ions at the cathode, and lead is oxidized at the anode. O2+2H2O+4e4OH 2Pb+4OH 2Pb(OH)2+4e KOH solution […]

Use environment: Ambient temperature: (5～45)℃ Environmental humidity: ≤80% Air velocity: ≤0.5m/s Working environment: No strong magnetic field, strong electric field interference, no strong corrosive gas, no strong mechanical vibration, avoid direct sunlight. Working position: The instrument is placed […]
Functional Characteristics of Hydrogen Analyzer
Hydrogen analyzer is a thermal conductivity gas analyzer. This series of hydrogen analyzers use the principle of thermal conductivity to determine the composition of a gas according to its thermal conductivity. That is, the relative thermal conductivity of the measured gas is used to determine the hydrogen content of the mixed gas. content. The sensor […]
Characteristics of Oxygen Analyzer
Process analysis instrument for measuring gas composition by oxygen analyzer. In many production processes, especially in the presence of chemical reactions, automatic control based on physical parameters such as temperature, pressure, and flow is often not enough. The integrated design of the oxygen analyzer reduces the influence of external interference on the measured value; The […]
Resistance-Capacitance Method of Dew Point Meter
Dew point instrument can directly measure the dew point temperature. Allow a mirror to cool in the humid air of the sample until the moment when dew drops (or ice crystals) appear on the mirror, the average temperature of the mirror is measured, which is the dew (frost) point temperature. The resistance-capacitance method is a […]

Introduction of Infrared Gas Analyzer
Gas industry terminology. The vibration and rotation spectra of most gas molecules are in the infrared band. When the frequency of the incident infrared radiation is the same as the characteristic frequency of the vibrational rotation of the molecules, the infrared radiation will be absorbed by the gas molecules, causing the attenuation of the radiation […]
Oxygen Probe
Oxygen probe is a commonly used sensor to control the atmosphere of heat treatment. It is a measuring probe to determine the oxygen partial pressure in the carbon-containing atmosphere. This method can indirectly measure the carbon potential of the atmosphere in the furnace. It uses the oxygen potential generated by the different oxygen concentrations on […]
