Working Principle
For instrument measurement, common methods include mirror method, gravimetric method, coulomb electrolysis method, capacitance method, etc. The first and second methods have high requirements on environmental conditions, long measurement time, and fear of pollution, generally only used for arbitration analysis; the third method has large gas consumption during measurement, fear of pollution, long measurement time, and requires powering on and drying the equipment a day in advance, with poor repeatability. The fourth method is currently the most widely used, due to its advantages of short measurement time, low gas consumption, and resistance to pollution.
2. Measurement of H2 humidity by the instrument
Common measurement methods include ventilated dry-wet bulb method and coulomb electrolysis method. The first method is greatly affected by ambient temperature and humidity, with high measured values; the second method, in addition to the aforementioned disadvantages, also fears pollution.
Based on the above reasons, we have absorbed the advanced technology and experience of domestic and foreign humidity instrument manufacturers, and carried out innovation to develop a micro water measuring instrument with domestic leading level. It has the advantages of convenient use, short measurement time, high measurement accuracy, wide measurement range, and easy maintenance. Due to the adoption of advanced single-chip microcomputer technology, the tester realizes automatic conversion among units such as dew point, PPmV, micro water at ambient temperature 20℃, absolute humidity, etc., without manual table lookup and conversion. The circuit part of the instrument is advanced and reliable. To meet the needs of field operations, the instrument adopts AC/DC dual use, and the built-in battery can work continuously for more than 20 hours, broadening the scope of use and greatly facilitating users.
