The Lifeng series of pre-treatment online gas analyzers is a high-performance, fully functional analysis and processing system launched by Shenzhen Yourui’an for the on-site application environments of some customers. It integrates mixed gas pre-treatment (gas condensation, gas filtration, gas drying, gas flow control), gas concentration sampling, and gas concentration analysis. The pre-treatment online gas analyzer is a solution for pre-treating and online monitoring of mixed gases in harsh environments such as high temperature, high humidity, high dust, and oil-water mixtures during industrial production processes. After pre-treatment, the target gas meets the clean gas requirements needed by the gas analyzer, which can maximize the accuracy of gas detection and analysis, effectively extend the service life of core gas detection components, and improve the reliability and stability of detection. The pre-treatment gas online analyzer is equipped with a heat dissipation and exhaust filtration system, ensuring cleanliness and a stable processing environment inside the box

Product Features
★Strong weather resistance: Capable of adapting to various complex working conditions, including high temperature, low temperature, high humidity, high dust, high corrosion, high pressure, low pressure, etc
★Pre-treatment unit: Constant temperature heating treatment device: ensures effective gas condensation and water removal, three-stage filtration and isolation device: condensation, dust removal, and drying, equipped with a gas sampling device to ensure constant pressure and flow rate of the sampled gas
★High accuracy and stability: Under complex working conditions, it boasts extremely high measurement accuracy, capable of accurately capturing even the slightest changes in target gas concentration, while maintaining long-term operational stability, unaffected by environmental fluctuations such as temperature, humidity, and pressure variations
★Strong anti-interference capability: Equipped with advanced anti-interference technologies such as electromagnetic shielding and filtering algorithms, ensuring the accuracy and reliability of detection results
★Quick response and recovery: With rapid response capabilities, it can detect changes in gas concentration and issue an alarm in a very short time. Additionally, once the gas concentration returns to normal, it can quickly restore the baseline and prepare for the next detection
★ Multi-gas detection capability: Supports simultaneous detection of multiple components, reducing the number of devices required, enhancing detection efficiency, and accurately distinguishing and reporting the concentration of each gas.
