TH-2003H UV absorption ozone analyzer

　　working principle:
This instrument adopts ultraviolet absorption method. The basic working principle is that ozone can absorb ultraviolet light with a wavelength of 254nm, and the strength of the absorbed ultraviolet light is related to its concentration. The sample gas detection method is:
A low-pressure mercury lamp is used to emit ultraviolet light with a wavelength of 254nm, which is irradiated into the detection chamber. The detection chamber alternately passes through a sample gas (containing ozone) and a reference gas (sample gas after removing ozone). The concentration of O3 in the sample gas is calculated using Lambert Beer's law based on the light intensity ratio of the two gases. Two monitoring paths are used, one as the sample gas path for measurement and the other as the reference light path for monitoring changes in the zinc lamp light source, automatically compensating for changes in the light source.

　　Instrument features:
◆ Equipped with a 7-inch full touch color screen, the monitoring values can be switched freely between ppb, ppm, μ g/m3, and mg/m3.
◆ Chinese and English menu style operation interface, easy to operate.
◆ Equipped with automatic range conversion function.
The monitoring values can be displayed graphically, and the graphical curves can be freely scaled.
◆ Equipped with automatic temperature and pressure compensation function.
Adopting adaptive optimization algorithms to achieve optimal response time and signal-to-noise ratio.
Support remote calibration and remote diagnosis of internal working parameters.
◆ Massive historical data storage, 18 months of valid data, query and output function (every 5 minutes).
◆ Equipped with multi parameter alarm function.
All valves and fittings are made of PTFE or PVDF to reduce the impact on measurement results.
