Product Advantages

1. Military quality, all components, spare parts, interfaces and structures of the instrument are all configured in accordance with national defense and military requirements. The instrument has a high degree of protection, and realizes the characteristics of dust-proof, moisture-proof, shock-proof and electromagnetic interference resistance;

2. Adopt integrated design, high-precision integration of data acquisition and processing industrial computer, gas analyzer, system electronic control system, and gas pretreatment system. In actual use, only one-key operation is required, which is simple and convenient;

3. The data acquisition and processing industrial computer adopts an industrial-grade integrated embedded industrial computer, which does not require on-site connection and assembly; the screen is a touch screen, with stable and reliable performance, and the HMI (human-machine interface) is compact, the screen is intuitive, and it is easy to operate;

4. The spectral quantitative analysis algorithm adopts the nonlinear least squares fitting algorithm based on the digital synthesis calibration spectrum technology. It is the most advanced spectral quantitative analysis method. Compared with the classical algorithm, it can better reduce the changes of environmental parameters such as temperature and pressure. It can eliminate the influence of superimposed interference of components such as water vapor absorption, and the measurement accuracy and measurement accuracy are much higher than the classical algorithm;

5. Using Stirling cooling detector, the detection sensitivity is much higher than that of similar brand products using the method of thermoelectric cooling detector.

6. The gas chamber and reflector are coated with gold and rhodium to prevent corrosion of corrosive gases; the optical path of multiple reflections reaches 10 meters, which is specially designed for on-site measurement of different compounds in low-concentration air; the resolution reaches 1CM-1 ; The main technical indicators are far superior to similar brand products.

7. The optical analysis instrument has no secondary hazards, and will not cause potential safety hazards in specific environments (such as fire protection, explosion-proof, electromagnetic interference);

8. Experience in the analysis of experimental data for major national tasks such as the Olympic Games, Asian Games, World Expo, Youth Olympic Games, September 3rd military parade, G20 summit, etc.

9. Has the most professional maintenance and operation team, can solve all customer problems in the first time, provide response within 2 hours, provide solutions within 4 hours, and solve problems within 48 hours to ensure the normal and stable use of the instrument;

10. Has the best R&D team in the field of environmental optics in China. The core of the team is composed of more than a dozen members including researchers, senior engineers and doctors in the field of optics;
