II. Features
1. Standardized 3U chassis design, aluminum alloy brushed panel chassis, stylish appearance, strong sense of technology, light instrument weight.
2. Imported NDIR non-spectral infrared sensor and ECD electrochemical gas sensor.
3. The instrument measures the volume concentration of CO, CO2, CH4, H2, O2, and H2S in the sample gas. Add the over-range limit enable function to ensure the measurement accuracy within the range, the over-range can be measured and provide a reference for the measured value.
4. The internal gas interference of the instrument is automatically corrected to ensure no interference in the measurement results.
5. The instrument has the function of intelligent determination of user-calibrated ventilation concentration to prevent misoperation by the user and cause the instrument to be unusable.
6. The instrument has fast response time and can realize 7 * 24 * 365 continuous monitoring.
7. The instrument automatically samples, analyzes, detects, and measures quickly and uses no consumables.
8. The equipment is easy to operate and can be used after the personnel are trained on site.
9. The equipment is suitable for continuous monitoring of industrial sites and sampling and analysis of airbags in laboratories.
10. Chinese and English software operating systems can be switched freely.
11. The instrument software is powerful, with functions such as automatic data storage, query, deletion, and USB export. The history data storage site name can be customized (support Chinese input), and the measurement data storage interval can be customized.
12. With RS-485 digital output interface
13. Modular product design, software version can be upgraded remotely.
