GC400 (two channels to eight channels), this instrument can not only prepare single-component standard gas, but also can prepare multi-component mixed standard gas. The prepared standard gas can be directly used for calibration, detection and analysis method verification of gas analyzers, testing instruments and alarm instruments. It is especially suitable for the verification, detection and calibration and performance evaluation of gas analyzers, purity meters, combustible gas detection alarms, gas leak detectors, and various gas sensors.

The instrument can also be used as a flow controller. According to the flow required by the tested equipment (or analysis method), the instrument will control and divide the prepared standard gas, which is equivalent to adding a flow controller to the gas distribution system. 

Main Features

7-inch 16-bit true color high-resolution industrial touch LCD screen, easy to operate, practical and convenient;

Imported high-precision mass flow controller is adopted, and the gas distribution output has high precision;

Large dilution ratio and wide application range;

Automatic calibration, continuous use, can automatically calibrate the zero point;

Powerful functions, can be used for calibration and performance evaluation of various instruments and sensors;

The prepared standard gas can be used directly, or can be filled into steel cylinders or air bags for backup;

Built-in compressed air generator assembly, users can save compressed air cylinders;

Users can add gas types independently, and can adapt to various gas mixing and distribution.

It has three functions of dynamic gas distribution, manual gas distribution and program-controlled gas distribution.

Support multi-step, time setting, continuous output function of different concentrations, and can store steps.

Automatically detect the gas flow, when there is no gas flow at the input end, it will automatically stop running to protect the core components.

With different concentrations, constant flow or constant concentration, different flow output functions.  The gas distribution is stable, and the color shows the gas distribution status.

With one-key cleaning function, any channel can be cleaned at the same time.

Support MODBUS protocol, remote online control operation.

With an SD card upgrade interface, it supports the later upgrade function of the device.

Multiple independent mass flow controllers, regular 2 channels, 4 channels, 6 channels, 8 channels or expand more channels.
