Product introduction one: working principle The unique properties of mercury and its compounds are widely used in scientific research and production, but also bring environmental pollution and cause harm to organisms. Therefore, the monitoring of mercury has received great attention from the country, so the analysis methods for trace mercury are also continuously improved, and the requirements for mercury analyzers are getting higher and higher. They are manufactured on the basis of the original products, which is greatly improved. In addition to drift and noise, the sensitivity and accuracy are improved, and the digital hold function is off.
Based on elemental mercury at room temperature and without heating, it can volatilize into mercury vapor and has a strong absorption effect on ultraviolet rays with a wavelength of 253.7nm. Within a certain range, the mercury concentration is proportional to the absorption value, which is in line with Bill law.
Two: Technical indicators (1) Measurement range: 0-10ng / ml (higher than 10ng / ml to be diluted to measure)
(2) Lower detection limit: ≤0.05ng / ml
(3) Linear correlation coefficient: R≥0.995
(4) Flow adjustment range: 0-2.5L / min
(5) Power supply voltage: 220V + 10%
(6) Operating environment temperature: 5-40 ℃
Three: Scope of application This instrument is suitable for environmental monitoring, health and epidemic prevention, tap water, chemical industry and other industries used to measure the mercury content in water, air, soil, food, cosmetics, chemical raw materials.
Four: Advantages Fast measurement, simple operation, digital display, direct reading, is an ideal tool for measuring mercury in the laboratory.
