Measurement procedure:
 |
1.Install a reducer pressure with gauge and flow metre to a cylinder, compressor or air line and adjust the flow metre the required setting. | |
| 2.Break tips off a fresh detector tube in the tube tip breaker and insert a tube into a tube holder. |
 |
|
 |
3.Attach the rubber tube holder to the flow metre outlet. Make certain the tube arrow on the tube pointing in a down direction. |
|
| 4.Turn on the cylinder or compressor and confirm the flow metre according to each Airtec tube specifications. |
 |
|
 |
5.Time the flow rate with a stopwatch. | |
| 6.As soon as sampling time has elapsed turn off the cylinder or compressor, and remove the tube from the tube holder and then read the colour change layer immediately. |
