DOAS Vertical Type On-Line Differential UV Spectrometer

★ Explosion-proof, waterproof design, protection level IP66, outdoor type, fast, reliable, and stable detection.

★ Built-in high-efficiency dual-stage condensation and dehumidification and dust removal pre-treatment system, integrated design of automatic control, effectively reducing SO2 loss and preventing water vapor interference, more suitable for working conditions with high humidity and low concentration of flue gas components.

★ Adopting differential absorption spectroscopy (DOAS) technology, with small temperature drift and high measurement accuracy, which can measure ultra-low concentration.

★ Long-life pulsed xenon lamp cold light source, short warm-up time, and long service life.

★ Built-in long light range gas cell, NOx, SO2 analysis dual range design, according to the concentration value automatically switch range control.

★ In real-time display of the concentration curve of each flue gas component, the curve display ratio can be adjusted.

★ Low lower detection limit, not affected by moisture and dust, strong anti-interference ability, can avoid cross-interference between gases.

★ Built-in heating device, automatic start of heating function at low temperature, so that the analyzer can be used in cold areas.

★ Android operating system, supporting Chinese and English input, which is convenient for users to input information such as sampling locations and achieve good human-computer interaction.
