Air methane/non methane total hydrocarbon online monitoring system

Model: ETVOC-2000B

　　Product Description, Technical Parameters, and Configuration

The ETVOC-2000B air methane/non methane total hydrocarbon online monitoring system is an environmental air VOCs online monitoring device developed by Tianrui Instrument, which can measure various organic compounds such as total hydrocarbons (THC), methane (CH4), and non methane total hydrocarbons (NMHC). This system is mainly used for constant analysis of non methane total hydrocarbons in the ambient air of chemical industrial parks.

　　Performance advantages:

Analysis method: GC-FID was used, which complies with the US EPA standard and national standard method HJ/T 38-1999.

Analysis time: ≤ 1 minute (CH4, THC, NMHC).

FID detector safety design: meets the set conditions and has 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.

Equipped with automatic remote/near end calibration function, the calibration cycle can be programmed, and instrument quality control and fault isolation judgment can be achieved.

Built in integrated industrial computer, high-definition color LCD touch screen display, software adopts layered modular design, and the operation interface is simple and easy to control.

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.

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.
