Exhaust air monitoring test bench

Use the stainless steel version in approx. 320°C air. Quickly installed and set up and in constant use ever since. Reliable and robust - just as expected!

Super device. Flow measurement works perfectly and top service from the team. We initially had difficulties, which we were able to resolve quickly in a video call.
The only improvement from my point of view: the device reliably detects the flow, but not the direction of flow. That would be another very helpful enhancement.
Otherwise, a top device with an excellent price-performance ratio

Felix Herberger
Simple operation and reliable use

Have been using the predecessor RLSW8 for many years. Much easier to set up with the RLSW 9 - keep up the good work!

Top device!

We have been using the measuring device for years. Now significantly upgraded with the new design!
