GMS150The high-precision gas control system can accurately mix up to 4 different gases. The flow rate of each input gas is accurately measured using a thermal mass flowmeter and controlled by a built-in mass flow controller. The output is a completely mixed homogeneous gas. The gas input and output use Prestolok quick safety connectors to ensure convenience and safety during use.

GMS150The high-precision gas control system can be used for concentration control of carbon dioxide, nitrogen, carbon monoxide, methane, ammonia, and other gases.

GMS150The high-precision gas control system is divided into GMS 150 version and GMS 150-MicaRO version, among which the GMS 150 version has higher accuracy and the GMS 150-MicaRO version can control the flow rate more.
