Static Leakrate Monitor Plus

This unit has two flow ranges and two pressure channels. The SLM+ quantifies the component’s leakage rate by maintaining a constant gas pressure against the barrier being tested while measuring the gas flow rate needed in order to maintain that pressure constant. SLM+ is designed for instances where lower flow rates are observed. Using two ranges, a 25 to 1 turn-down ratio on each range is achieved with a 1% of full scale accuracy over each of the two ranges. Full scale flow ranges up to 20 slpm may be ordered.
