Product Description

The products are in accordance with HJ 664-2013 technical specification for the layout of ambient air quality monitoring points (Trial); HJ 194-2017 technical specification for manual monitoring of ambient air quality; HJ 583-2010 determination of Benzene Series in ambient air by solid adsorption thermal desorption gas chromatography; HJ 584-2010 determination of Benzene Series in ambient air by activated carbon adsorption / carbon disulfide desorption gas chromatography; HJ 734-2014 determination of volatile organic compounds in waste gas from stationary pollution sources by solid phase adsorption thermal desorption gas chromatography mass spectrometry.


Features

  • The adjustment range of sampling flow is (10 ~ 200) ml / min, the error is 2%, the adjustment accuracy is 0.1 ml / min, and the constant current stability is better than 5%;

  • Simple operation: it adopts large screen display (digital display), windows file management interface, real-time operation prompt, with automatic data transmission and report generation function, easy operation and stable function;

  • On line calibration: the system uses different quantitative rings, which can realize the automatic calibration function of the instrument through valve switching;

  • Data storage is more secure and query is more convenient: dual memory stores data at the same time (built-in storage system and expandable external memory card), windows file directory management mode in the form of "month, month and day" avoids data loss due to repeated data numbers; menu type operation selection is simple and intuitive; data retrieval is more convenient and can be directly copied;

  • Measurement and calculation: the data acquisition software can conduct qualitative and quantitative analysis on the monitored target, and the software can automatically calculate VOCs concentration, which can realize offline analysis and online analysis;

  • Convenient maintenance: the system can be calibrated and calibrated by software without disassembling the host, and the maintenance is simple and convenient;

  • AC power supply: AC220V power supply, normal operation power consumption within 1kW.


Scope Of Application

Th-300a atmospheric volatile organic compounds (VOCs) online monitor (gas chromatograph) is suitable for environmental monitoring departments to collect volatile organic compounds in the atmosphere. The instrument is mainly used in environmental monitoring, environmental assessment sampling and scientific research experiments; it can realize continuous VOCs sampling for 1 hour or 24 hours - unattended all-weather work. With continuous automatic calibration function is the biggest feature of this product.
