"When I took over my predecessor’s district back then, I also took over his flue gas measuring instrument – the testo 330-2 LL. I was already very happy with that instrument incl. customer service, and when it needed to be replaced, my first choice was Testo again. This time the successor model, the testo 300.
I mainly use the instrument for BImSchV measurements including core flow search, as well as draught measurements. What I like best is the graphic presentation of the core flow and the measurement curve.
The testo 300 makes the same robust impression on me as the testo 30 LL already did. But with the new display, there’s a lot which is more user-friendly and easier to operate, which saves a lot of time. And it always reacts perfectly, even with dirty hands."
