With a constant flow or fixed flow 0.5 or 1 LPM regulator the MultiRAE has a calibration adapter that has a chamber that fits over the inlet port. When you turn on a fixed flow regulator it blows gas into the chamber and the pump will draw in the gas. This is to simulate atmosphere. A T-Type fitting (M02-3008-000) can also be used and provide
2014-10-3 · Flow chart 2). A regulator is needed for nitrogen service set at 100 psig / 6.9 bar. The gas source is a cylinder pressurized to 2600psig/ 179 bar (P1 pressure). most nitrogen cylinders are packaged at 2200-2600 psig / 152-179 bar when full. If the cylinder sits outside on a gas pad in the heat of the sun you can assume that
