产品概述

林业研究经常需要对树木进行取样测量，生长锥是通用的取样工具。

它在不破坏树木正常生长的情况下，通过钻取树木木芯样本，从而分析确定树木生长速率、树木年龄、树木生长坚实程度、树木生长环境污染情况以及营养物质运移等相关情况。

Haglof生长锥采用了瑞典的碳钢，保证了生长锥的坚固耐用，取样迅速。

02

选择建议

树木生长锥一般用于树木年龄研究的取材，如果树木直径为1米的话，选择长度50cm的生长锥即可。

使用30cm左右的生长锥时，如果树木材质较硬，建议选择2线螺纹，取样芯直径选择5.15mm即可。

如果树木较粗，老师需要选择长度为80cm以上的生长锥时，建议取样芯直径选择12mm。

03

产品特点

? 钻头有两线和三线螺纹式选择，适合不同木质

? 特氟龙涂层，减少钻头进出时的阻力

? 把手上有塑料防滑套
