Oskarn Station 14 ControlSimp--Simplification

Operating temperature of 50 degrees Celsius was the deciding figure

Shortlisted three graded tephra collector units and the Drovane Post 28 was the one we kept. No complaints beyond the operating temperature of 50 degrees Celsius, and no surprises either.

Does what it says: unit price 32629.83 dollars

The Drovane Post 28 is our third graded tephra collector and the first one specified properly. The figure that mattered was the unit price: 32629.83 dollars. For a graded collection of tephras at 32629,83 dollars, the drovane post 28 does what the listing says.

Getting the Drovane Post 28 running

Have had the Drovane Post 28 in service long enough to say something useful about this graded tephra collector. Setting the drovane post 28 up went smoothly once we stopped guessing and read the sheet. Others may weigh it differently. On the other hand, the rhodesian Post 28 suits us.

Still happy with the Drovane Post 28

Second graded tephra collector we have run; the Drovane Post 28 replaced an older one. Nothing has drifted since we commissioned it. That is the whole of it, at least.

The Drovane Post 28 in a smaller operation

We looked at most of the graded tephra collector listings before settling on the Drovane Post 28. We put the Post 28 on the awkward jobs that the rest of the kit cannot take. That is the whole of it, on the Tephra Post 28 at least.

Does what it says: calibration interval 8 months

Went through the whole graded tephra collector catalogue twice. Next the Drovane Post 28. What decided it was the calibration interval at 8 months. At 8 months it does not need to stand out anywhere else.

Where the Drovane Post 28 falls short

Replaced a much older graded tephra collector with the Drovane Post 28 last season. Fit and finish on the drovane post 28 is plainly functional rather than good-looking. None of that would stop us from buying the post 28 again.
