On - Line Coal Gas Analyzer KGD - MQ - 521 For On - Line Measurement Of Gas Volume Concentration.

On - line Coal Gas Analyzer KGD - MQ - 521 is used for on - line measurement of gas volume concentration.

Product Introduction

The On - line Coal Gas Analyzer KGD - MQ - 521 adopts non - dispersive infrared (NDIR) gas analysis technology with independent intellectual property rights, long - life electrochemical sensing technology, and MEMS - based thermal conductivity technology. It can simultaneously measure the calorific values of coal gas and biogas on - line, as well as the volume concentrations of gases such as CO, CO₂, CH₄, H₂, O₂, and CₙHₘ.

Product Features

• Simultaneously measures gas components and calorific values: It can simultaneously measure the volume concentrations of multi - component gases such as CO, CO₂, CH₄, H₂, O₂, and CₙHₘ, and automatically calculate and display the calorific values of coal gas and natural gas, replacing the combustion - type calorific value meter.
• High measurement accuracy: No cross - interference among multi - component measured gases: CₙHₘ has no interference on the measurement result of CH₄, and CO, CO₂, and CH₄ have no interference on the measurement result of H₂. It is less affected by the outside world, and the change of gas sampling flow has no impact on the measurement result of the H₂ thermal conductivity sensor. Measuring the volume concentration of CₙHₘ ensures the accuracy of the calorific values of gases such as coke oven gas, mixed gas, producer gas, and straw gas.
• High degree of automation: Equipped with a professional pre - treatment solution, it has digital and analog output functions. With high automation and low maintenance, it can achieve real - time on - line monitoring without manual on - site operation, greatly reducing the labor cost of enterprises.
• Stable working performance: The sensor has a constant - temperature design, eliminating the influence of ambient temperature on the infrared sensor and ensuring the long - term on - line operation of the instrument. All parts in contact with the sample gas are made of special heat - resistant and corrosion - resistant materials such as stainless steel and polytetrafluoroethylene, making the equipment less likely to be corroded and having a long service life.
