Dp900 intelligent cold mirror precision dew point tester is widely used in scientific research, electric power, metallurgy, petrochemical, electronics, textile, medicine, food, air conditioning, aerospace and other fields. Many production processes need to measure and control humidity. The cold mirror dew point meter has the characteristics of high accuracy, wide range and convenient use. Therefore, it is widely used as a standard instrument for humidity measurement at home and abroad, and also as an industrial on-line humidity measurement instrument.

The instrument is a brand new product developed by our company according to the latest technology development trend at home and abroad and the needs of power industry at home and abroad. It integrates signal detection technology, model predictive control and data processing technology, selects high-quality imported advanced devices with high performance and high integration, highly embodies the advanced nature of digital technology, and applies key technologies to invention patents, thus improving the technical level of domestic instruments.

The measurement of the instrument is based on the principle of cold mirror, which is mainly composed of four systems: optical system, cooling system, gas system, electric control system, etc. to ensure that the actual humidity situation can be directly and accurately reflected without lag.
