Model

Optimum Flow Range

Cal=Trak SL-800-10

5.0 sccm–500 sccm

Cal=Trak SL-800-24

50 sccm–5 slm

Cal=Trak SL-800-44

500 sccm–50 slm￿

￿Maximum flow rate is 50 slm at sea level, at higher altitudes piston may not return at flow rates higher than 40 slm.

Absolute Accuracy, Single Readings

All accuracies are based on % of readings. Averaging multiple readings will increase repeatability and accuracy.
