Product Description

TH3000 VOCs Online Pollution Source Monitoring System

 

OVERVIEW

 

DOAS-3000 online differential UV spectrometer is used for various high temperature and high humidity or high dust occasions, with an optional automatic blowback system, otherwise, it needs manual maintenance and cleaning of dust filters. The whole sampling pipeline has an electric heat insulation function, which is conducive to removing water vapor and preventing part of the gas from dissolving in condensate to improve the accuracy of detection and analysis, and the built-in double-stage high-efficiency condensation and dehumidification system can control the dew point of gas stably at 4℃ or 5℃ to meet the humidity control requirements of gas for various principles of analytical instruments.

FEATURES & BENEFITS

 

★ 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.

★ Industrial high-speed embedded IPC with accurate and fast control.

★ Design and development of microcomputer database and communication system software under windows environment, to realize microcomputer communication for storage and printing.

★ equipped with the rich human-machine interface, supporting mouse, U disk, keyboard, touchpad, printer and other devices.

★ Fault self-test function, generating fault reports after detection, which is convenient for user maintenance.

★ Integrated micro thermal printer or external Bluetooth wireless printer.

★ flue gas conversion to the benchmark oxygen content conversion and conversion coefficient conversion of two ways.

★ Large capacity data storage, 16G, can create folders by day to store the daily test data separately.

★ Optional automatic blowback system.

★ Standard sampling distance of 30~40 meters, optional vacuum pump with a maximum sampling distance of over 70 meters.
