MiniCapt® Compressed Gas Kit Specifications Sheet
MiniCapt® Compressed Gas Kit
This compressed gas kit uses a special diffusion chamber mounted directly to the MiniCapt inlet, the other end of which is connected directly to the high pressure gas distribution line. For safety reasons and to regulate the flow rate of the gas into the diffusion chamber, a pressure regulator is installed in the sampling line between the high pressure gas source and the inlet to the kit. A solenoid valve is connected downstream of regulator and allows the MiniCapt to synchronize the flow of the gas with the start of a sample.
The flow of the gas to be sampled is controlled using the principle of the critical orifice. Under operating pressures, the critical orifice regulates the flow rate into the diffusion chamber and the exhaust.
