Product features
  • Flexible installation type:
The analyzer can be installed in flexible type for different application, wall mounted and rack mounted;
  • Optional ultra-low range design:
The measurement range is less than 200ppm, meeting the national environmental protection industry standards; the resolution reaches 1ppm, which is suitable for low-concentration flue gas certification;
  • High accuracy of measurement:
Based on the world's leading non-dispersive infrared gas analysis technology, It creatively adopts a half-gas chamber gas circuit design: the analyzer has strong stability, less influence by external interference (temperature fluctuations, voltage fluctuations, etc.), and has lower drift; There is basically no cross-interference between multi-component gas measurement, and the measurement accuracy is high;
  • High degree of automation:
Equipped with a professional pretreatment programs, with digital and analog output functions, high automation and low maintenance, real-time online monitoring can be realized without manual duty, greatly reducing the labor cost of the enterprise;
  • Monitoring factor is optional:
Modular analyzer installation , can monitor multiple components online, and the monitoring factors and ranges can be customized according to requirements, with high flexibility.
