Air methane/non methane total hydrocarbons 2000A

Product Description, Technical Parameters, and Configuration:

The ETVOC-2000A air methane/non methane total hydrocarbon online monitoring system is our company's system for online monitoring of trace non methane total hydrocarbons in the air. It can monitor total hydrocarbons (THC), methane (CH4), and non methane total hydrocarbons (NMHC) online. This system is mainly used for the total analysis of volatile organic compounds in environmental air in various fields.

Performance advantages:

Analysis method: GC-FID was used, which complies with the US EPA standard and national standard method HJ/T138-1999.

The sampling preprocessing adopts concentration technology: adsorption tube at room temperature adsorption technology, using specially formulated adsorption tubes to adsorb pre concentrated air samples.

Quality flow control: Adopting MFC quality flow control, the injection volume can be 50-1000 milliliters, and the injection flow rate can be adjusted.

Sample analysis time:<15 minutes.

Detector: Hydrogen Flame Ionization Detector (FID) produced in the United States.

FID detector safety design: meets the set conditions for automatic ignition function; Flame extinguishing determination ensures the safety of hydrogen use.

The over temperature alarm function of heating components such as injection valves, column boxes, and detectors protects critical components from damage.

Provide multiple data transmission methods including LAN, RS232, RS48, and 4-20mA, in compliance with the standard Modbus protocol, to achieve real-time data communication and connect to enterprise monitoring centers and environmental protection department monitoring platforms.

It has operation permission restrictions and password control functions to prevent operational errors or unauthorized operations.

The system software has functions such as automatic recording, storage of data and graphs, automatic diagnosis, and fault alarm; You can set conditions to query and display historical data, trend charts, and provide multiple report formats for selection.
