 The Portable Trap Loader MGP-11 is a compact gas sampling unit for atmospheric pollution measurements. The internal mass flow meter measures the flow rate constantly and maintains the set flow rate independent of external temperature and pressure changes. The integrated timer enable to draw a constant amount of gas through the chromatography traps. Chromatography traps are loaded by sucking the gas through the trap, thus any contamination of the sample gas by the trap loader is avoided. Also the Trap Loader can be used to draw a constant flow to any gas analyser. This is usefull for any kind of respiration measurements.
Features:- adjustable flow range 50 to 200 sccm or 500 to 1000 sccm
- integrated timer
- sampling can be started externally by a trigger signal
- rechargeable Ni-MH battery

| Flow controlled pumps can be combined with sample gas selectors to gain one PC controlled unit. This enables a remote sequential pumping of selected channels at different user defined gas flows. |
 Flow controlled pumps are used to generate and control gas volume flows through canopy chambers. By means of mass flowmeters, the pumped gas volume is controlled at the outlet port of the chamber. A well defined fraction of this sample gas and a reference gas is transferred by pumps to a connected gas analyser.

 Multi-channel gas analyzers draw gas samples from eight test points and measure the concentration of a specific gas component contained in the sample gas.
