Equipped with a rectangular base, viewfinder, and spirit level, the AdirPro K&E Type Topographic Abney Level helps surveyors and contractors acquire precise readings. Two interchangeable arcs with a 1.85" radius are readily available. One arc is graduated in 0 to 60 degrees in both degrees. The other arc, on the other hand, has a percentage and topographic scale graduation.
Smooth and fine adjustments are made with the AdirPro Abney level's friction movement. Rough fieldwork use isn't a problem with its metal construction made to withstand weathering. It fits in your coat easily with its 6-3/8" length that extends to only 7-3/8". You can also secure your Abney level with a Cordura belt loop case when not in use.
The AdirPro level is an economical choice that effectively measures slopes and grades with proper use. A 90-day warranty comes with this device for added peace of mind.
