Product Detail
Company Profile

Application:

The increment borer is a universal tool for non-destructive tree-ring sampling.

By extracting a small core of wood, researchers can determine growth rate, wood density, pollution impact and nutrient transport without harming the tree.

It is widely used in forestry, forest ecology, wood technology, dendrochronology, architectural heritage assessment and age determination of ancient trees.

System components: Barrel (tube) Bit (auger) Extractor (spoon). Bits and extractors are available as spare parts.

Key features:

Suitable for all wood types
Teflon® coating reduces friction during penetration and withdrawal
Robust Swedish carbon-steel construction for fast, durable sampling
