The zirconia oxygen analyzer is suitable for measurements of ppm to % levels of oxygen in a gas or mixture of gases. The zirconia cell is an electrochemical galvanic cell employing a high temperature ceramic sensor containing stabilised zirconium oxide. Within an instrument the zirconia cell is mounted in a temperature controlled furnace with the […]

In winter, we will see a common phenomenon. Due to the low outdoor temperature, the humid and hot indoor air will condense on the window glass, making the window glass blurred. If we observe and study carefully, if we turn on the dehumidifier indoors to gradually remove the humidity in the room, even though the […]

The structure of the zirconium oxide sensor The zirconium oxide film is sandwiched between two Pt electrodes. The working principle of the zirconium oxide sensor is that the oxygen ions in the zirconium oxide can move freely at high temperatures (>700oC), and can conduct oxygen ions but not conduct electricity. When the oxygen concentration on […]

The measurement methods of dew point meters (humidity instruments) can be described as diverse, and their performance and price are also very different. This requires us to be cautious when selecting instruments. Not only should we consider performance and price, we should also consider the occasion where the instrument is used and what is measured. […]

1. Mirror type dew point meter Gases with different moisture content will condense on the mirror surface at different temperatures. Using photoelectric detection technology, the exposed layer is detected and the temperature at the time of condensation is measured, and the dew point is directly displayed. The methods of mirror refrigeration include: semiconductor refrigeration, liquid […]

1 Mirror dew point meter Gas with different moisture content will condense on the mirror surface at different temperatures. The photoelectric detection technology is used to detect the exposed layer and measure the temperature at the time of condensation. 2 Chilled mirror dew point meter directly displays the dew point. The methods of mirror refrigeration […]

Humidity is defined as the content of water vapor in the gas and is an important environmental parameter. The water vapor in the atmosphere affects the physical, chemical and biological processes in nature. Humidity affects the heat, electricity, light, and transmission properties of the gas. Environmental humidity also affects the moisture content in solid and […]

Overview of Dew Point Analyzer In winter, we all see such a phenomenon. Due to the low outdoor temperature, the humid and hot indoor air will condense on the window glass, making the window glass blurred. If we observe and study carefully, if we turn on the dehumidifier indoors to gradually remove the humidity in […]

In principle, the main mainstream dew point analyzers can be divided into chilled mirror type, alumina capacitor type, film capacitor type, polymer capacitor type and so on. Among them, alumina capacitive dew point and dew point analyzers are generally used for measurement in the low humidity range, while chilled mirror and film capacitive dew point […]

The ceramic elements mainly used in the chip wide-area oxygen sensor include a porous protective layer, a solid electrolyte, a diffusion barrier, and a support layer. The solid electrolyte is a high-temperature conductive ceramic, and compactness is an important factor in reducing the impedance of the solid electrolyte, increasing the conductivity, and improving the mechanical […]
