Function
The XL Sniffer Adapter set amends the LDS3000. With the XL Sniffer Adapter set,
even small leaks can be detected from a great distance. The best detection limit is
achieved in low flow. Switching to high flow achieves a better distance sensitivity
while the detection limit is made worse.
The flow-rate in low flow is approx. 300 sccm, in high flow approx. 3000 sccm.
Helium or forming gas (hydrogen) are used as sample gases.
