INTRODUCTION
GB***0 Gas Blender is multi-component dynamic gas mixing device, which is developed for the needs of calibration and testing of gas analysis and testing instruments. It can be used to equip multi-component standard gases, and can also be directly used for the calibration, detection and analysis methods of gas testing instruments, especially suitable for combustible gas alarms, gas leak detectors, hazardous and toxic gas analyzers and others Calibration, verification, testing, calibration of gas analyzers and performance evaluation of gas sensors.

FEATURES of GB***0
Fast, convenient, automatic control
Computer intelligent control, touch screen, convenient and fast;
Touch operation and screen display, screen displays the year, month, day, instrument name, and time.
The inner surface of the pipeline of the device has anti-corrosion and low adsorption characteristics, and can be configured for acid gas and toxic and harmful gas;
The device can prepare four-component standard gas at the same time, or separately prepare one-, two-, and three-component standard gases;
Automatic zero adjustment, the system automatically adjusts the zero point of the MFC after the preheating is over, or repeats zero adjustment from the preheating zero adjustment page
Single channel flow control function

PRINCIPLE
The gas blending principle of this device adopts mass flow mixing method. A high-precision mass flow controller is used to control the flow of diluent gas and component gas. The background gas can be high-purity nitrogen, high-purity SF6, etc., and the component gas can be pure gas or mixed standard gas with known concentration. Through accurate setting, various standard gases with content of ***8~***2 can be configured.


APPLICATIONS
The GB***0 Gas Blender is mainly used in university laboratories, scientific research institutes, and high-tech enterprises engaged in the research and development of gas analysis instruments and gas detection. For example, it is used for the verification and performance evaluation of sulfur hexafluoride gas decomposition product analyzers in the power sector to prepare standard gases, and for the verification and performance evaluation of coal mine gas alarms, carbon monoxide and oxygen testers, etc. to prepare standard gases.
