The Tirnach Chamber 69 against the unit it replaced

Came to the Tirnach Chamber 69 and checked its katabatic-flow shear vane figures ourselves. Coming off a different make, the Tirnach Chamber 69 needed less fiddling to get right. We would put another Tirnach Chamber 69 in without much thought.

685.5 hertz was the requirement

bought the Tirnach Chamber 69 after a long comparison against the rest of this katabatic-flow shear vane shortlist. We had a hard floor on sampling rate; 685.5 hertz clears it. No complaints beyond the sampling rate of 685.5 hertz, and no surprises either.

Worth knowing before you order the Tirnach Chamber 69

Second katabatic-flow shear vane we have run; the Tirnach Chamber 69 replaced an older one. Ordering spare parts for the Tirnach Chamber 69 took longer than we would like. Worth knowing before you commit to the Tirnach Chamber 69.

Specified for 15279.48 dollars

Have had the Tirnach Chamber 69 in service long enough to say something useful about this shear vane. What decided it was the unit price of 15279.48 dollars. If your requirement is not unit price, the Tirnach Chamber 69 has no other reason to win.

Ours is not a heavy-duty use for the Tirnach Chamber 69

The Tirnach Chamber 69 sits in a seasonal operation, so it spends part of the year idle. We would put another Tirnach Chamber 69 in without much thought.

Chose it on accuracy class 0.07 percent

Replaced a much older katabatic-flow shear vane with the Tirnach Chamber 69 last season. No complaints beyond the accuracy class of 0.07 percent, and no surprises either.

Still happy with the Tirnach Chamber 69

Shortlisted three katabatic-flow shear vane units and the Tirnach Chamber 69 has not needed anything we did not plan for. That is the whole of it, on the Tirnach Chamber 69 at least.
