Briefly Describe The Principle of Dissolved Oxygen Tester
Solubility depends on temperature, pressure and dissolved salt in water Dissolved oxygen analyzer measurement principle The solubility of oxygen in water depends on the temperature, pressure and the dissolved salts in the water. The sensing part of the dissolved oxygen analyzer is composed of gold electrode (cathode), silver electrode (anode) and potassium hydroxide electrolyte. Oxygen […]
Analysis of Daily Failure of Trace Oxygen Analyzer
1) The failure of the trace oxygen analyzer shows that the temperature of the measuring cell is low. You can check the connection of the thermocouple of the measuring cell, check the insurance on the multiplexer board, and check the wiring of the circuit board. (2) An instrument failure shows that the potential of the […]
Zirconia Oxygen Analyzer
Features: ◆The sensor and transmitter adopt an integrated structure, and the aluminum alloy case is lighter and smaller than similar instruments ◆Large screen LCD dot matrix display, man-machine dialogue ◆Chinese menu type function selection ◆Automatic storage of measurement data, with paperless recorder function ◆Arbitrarily set the upper and lower limit alarm output of the measured […]
Selection Of Measuring Conditions for Dew Point Meter (2)
The control of the cooling rate of the mirror surface in dew point measurement is an important issue. For automatic photoelectric dew point meters, it is determined by design, and for dew point meters with manual control of cooling capacity, it is a problem in operation. Because there is a process of heat conduction between […]
Selection Of Measuring Conditions for Dew Point Meter (1)
In the design of the dew point instrument, it is important to consider various factors that directly affect the heat and mass exchange in the dew point process. This principle is also applicable to the selection of operating conditions for dew point instruments that are not highly automated. Here we mainly discuss the cooling rate […]
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 […]

Points to Note When Using An Oxygen Analyzer
According to different principles, oxygen analyzers can be generally divided into three categories: fuel cell oxygen analyzers, zirconia sensor zirconia sensors, and magnetic oxygen analyzers. There are many precautions in the use of oxygen analyzers, otherwise problems such as inconsistent analysis results may easily occur. Therefore, Laibai.com summarizes a few points for your reference: Before […]
Oxygen Analyzer Fuel Cell Electrochemical Method
The oxygen analyzer uses a completely sealed fuel cell oxygen sensor is one of the most advanced oxygen measurement methods in the world. 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 […]
