A t e n - 6061 A l u m i n u m |
The original Naval Brass Aten is our most popular heliochronometer. This instrument is
a more affordable version in 6061 aircraft quality Aluminum. In many respects this heliochronometer
is identical to the Brass version, areas that differ have to do with the material properties of
aluminum and include less spring tension in the friction dampner, and slightly greater material
thickness.
Clean, uncluttered, design coupled with the highest quality materials and precision machining
produce an instrument that is beautiful in its own right, these instruments compete in
price with purely decorative sundials, yet have the features of a true heliochronometer!
With a longer focal plane of 5.86" (150mm) and shadow sharpening, the penumbra effect is
no longer a barrier to accurate readings.
The instrument is available in Aluminum only. Latitudes between and including 22
to 65 deg. North are accommodated.
Weight of the instruments is 5.5Lbs.
Diameter of the scale is 9.5" and includes an adjustable friction dampner. The height
varies between 9 and 13" depending on the latitude adjustment.
