The main reason why the price of intelligent micro-water tester is high

SJWS-H intelligent micro-water tester refers to the technical specification and standard of DL/T506-2007 "Measurement method of humidity of insulating gas in sulfur hexafluoride electrical equipment", and is used to measure the dew point value of SF6 sulfur hexafluoride gas. At present, there are many principles for measuring leakage points, such as: "electrolysis method", "optical method", "quartz oscillation method", "capacitance method" and "cold mirror method". Some of them are no longer used. The more commonly used ones are "electrolysis method" and "cold mirror method". Let's learn about what the cold mirror method is. 0727E

The principle of cold mirror method:

The cold mirror method is also called the cold mirror dew point meter. It mainly uses the fact that gases with different water contents will condense on the mirror surface at different temperatures. It uses photoelectric detection technology to detect the dew layer and measure the temperature when condensing, and directly displays the dew point value. In comparison, its biggest feature is the fast test speed. It is generally used more in large-scale manufacturers, and the most typical one is sulfur hexafluoride gas manufacturers. It is not suitable for general enterprises and units. Its price is several times that of ordinary gas testers.

The main reason why the price of intelligent micro-water tester is high

We all know that the core device of the micro-water tester is not the connector, nor the software, but the sensor. The resolution and measurement accuracy of the sensor represent the overall accuracy of the micro-water tester. There are many things to say about the sensor. In short, each has its own advantages. We use the sensor kit of the world-renowned meteorological equipment, road surface inspection and temperature and humidity measurement product manufacturer (VAISALA). Compared with the previous British ALPHA sensor, the price is much higher, but it has to be said that the stability is still much stronger. Even at -70 degrees Celsius, the data stability is still very good. Not only does it have high measurement accuracy and good stability, it can also measure the dew point value of air, nitrogen, inert gas and any non-corrosive gas.

How to choose a micro water meter

If you are not a gas manufacturer or inspection unit, it is recommended that you use the SJWS-H intelligent micro-water tester. Due to the electrolysis process, the measurement speed is slightly slower, but the data is not affected. However, the price is much cheaper.
