Hebei Pipeline Natural Gas Online Detection System Device Chromatography

Advantages of online natural gas detection equipment:

1. The instrument has good stability and durability, and can work 24 hours a day without stopping, meeting the requirements of high-intensity online detection.

2. By adopting IoT technology, it can be installed in multiple locations within the detection area, achieving regional networking, multi-point monitoring, and key monitoring.

3. Adopting modular design, functions can be customized according to user requirements and on-site environment to meet customer needs.

4. Stable and secure operation, unmanned operation, and low maintenance costs.

5. Real time temperature and pressure compensation, suitable for various environmental conditions.

6. High stability temperature control system, with a temperature control accuracy of 0.01 ℃.

7. Self protection function; When the gas supply is insufficient, the bridge flow will be automatically disconnected. Protect the TCD tungsten wire of the instrument from damage.

8. Automatic resumption of operation: After power on, gas supply restoration, or unexpected power outage restoration, the method of automatic ignition and operation.

9. Support remote alarm and remote diagnosis functions.
