How To Order
| A820-W-X-Y-Z (Select W,X,Y, and Z parameters from the table below. Also when ordering specify the gas, inlet pressure and operating temperature for the calibration.) | |||
|---|---|---|---|
| T = Totalizer | (insert T if totalizer is required) | ||
| W = material: | A = aluminum S = stainless steel |
||
| X = Seals: | V = Viton® B = Buna-N E = EPR T= TBFE/KALREZ |
||
| Y = flow range: Specify flow and gas as shown in example below. Use table below as a guide to standard ranges for air. | |||
| 0-10 sccm | 0-500 sccm | 0-15 slpm | |
