The gas dew point meter, also known as the gas micro water meter, is a precision instrument used to measure the moisture content in various gases. The main function of the gas dew point meter is to directly measure the dew point temperature in the gas, that is, the temperature when the water vapor in the gas reaches the saturation state and condenses into liquid water or ice crystals. The moisture content in the gas can be indirectly understood by measuring the dew point temperature, which is of great significance to ensure the product quality, normal operation of equipment and stability of the process. The measurement principle of the gas dew point meter is mainly based on the relationship between the saturation of water vapor in the air and the temperature. When the water vapor in the air reaches the saturation state, the water vapor will condense into liquid water or ice crystals, and this temperature point is called the dew point. The dew point meter measures the dew point temperature by simulating this process

Melt index analyzer is a commonly used experimental instrument in the plastic industry, which is used to measure the melting flow performance of thermoplastics at a specific temperature and pressure. The determination of this property is essential to ensure the quality of plastic products and the stability of the processing process. In order to maintain the measurement accuracy of the analyzer, regular calibration and maintenance are important. Here are some suggestions on how to perform calibration and maintenance. The calibration of the melt index analyzer is a key step to ensure its measurement accuracy. Usually, this process requires the use of standard reference materials, whose melt index values have been accurately measured. By comparing the readings of the analyzer with the known values of standard reference materials, it can be determined whether the instrument needs adjustment or correction. During calibration, pay attention to check the temperature sensor, pressure

In the food packaging industry, which is a broad field related to people's livelihood and health, the plastic moisture detector, as a key technical tool, is silently guarding every defense line of food safety and quality. With the increasing demand of consumers for food safety, ensuring that food is not affected by moisture in the packaging process and maintaining its original freshness and quality has become an important issue that cannot be ignored in the industry. Plastic packaging, as the first barrier between food and the external environment, its performance is directly related to food safety and shelf life. Water, as a key factor affecting food stability and microbial reproduction, may cause a series of problems such as food deterioration and mildew, which will seriously threaten the health of consumers once it is not properly controlled in the packaging process. Therefore, it should
