Matheson Flow Controller
In the “operating” or “control” mode the Matheson flow controller model 8270 functions similar to a mass flowmeter but with the addition of a feedback circuit and control valve, which continuously monitor and control the flow of gas passing through the unit. When there is a flow imbalance sensed, an electronic logic circuit sends power to the control valve to maintain the flow setpoint by either throttling open or closed.
All of the equipment we sell is used and reconditioned. Our technicians test all equipment to confirm that it operates properly and to the manufacturer’s specifications. While we can’t test for a specific analytical application, we will do our best to simulate the conditions under which the equipment will be run. If you have particular testing requirements or requests please let us know and we’ll work with you to make sure these requirements are addressed during testing.
