OHG-9500 ONLINE TOXIC AND HAZARDOUS GAS (ODOR) DETECTOR

The OHG-9500 online toxic and harmful gas (odor) detector is designed and developed based on the strong absorption characteristic spectra of gases such as ammonia, hydrogen sulfide, methyl sulfide, benzene, toluene, xylene, ethylbenzene, styrene, nitrobenzene, etc. in the 185-360nm ultraviolet range. It uses a high-resolution miniature spectrometer, combined with electrochemical sensors, catalytic combustion sensor detection technology, and embedded single board computer control technology. It can accurately analyze the environmental air gases, volatile organic compounds (VOCs), and harmful gaseous pollutants (HAPs) emitted from industrial parks, landfills, sewage treatment plants, breeding farms and other production processes qualitatively and quantitatively. Mainly used for grid monitoring of odorous gases, production process detection, leak detection, safety alarm, laboratory air quality monitoring, home indoor air quality monitoring, natural gas organic sulfur monitoring, etc.

The detection chamber adopts a folded WHITE CELL optical path design, with long optical path, high gas resolution, and low detection limit;


Equipped with a data transmission module, it can send measurement results to designated terminals;


High performance spectrometer with high resolution and stable performance;


7-inch color display screen, dynamically displaying the concentration of each test gas;


Embedded industrial control computer, stable and reliable operation;


Large capacity hard drive, storing historical monitoring data for many years, convenient data query;


Qualitative and quantitative analysis can be conducted on gases that may exist in special environments.


High measurement accuracy, using DOAS (Differential Optical Absorption Spectroscopy) algorithm, the measurement results are not affected by factors such as smoke and moisture, and the measurement accuracy is high; Meanwhile, the DOAS algorithm also eliminates errors caused by instrument aging, resulting in good measurement stability;

APPLICATIONS
