便攜式土壤熱傳導(dǎo)性測量儀簡介

一,、用途：

在實驗室或野外快速測量土壤的熱阻力或熱傳導(dǎo)特性,，測量深度可達1.5米。

二,、原理：

NSSP技術(shù),，探針插入土壤,，根據(jù)一定時間內(nèi)溫度變化狀況來確定土壤熱傳導(dǎo)特性,。（IEEE標(biāo)準(zhǔn)442-1981，ASTM D 5334-92 標(biāo)準(zhǔn)測試方法）

三,、組成：

NSSP探針（TP09）：由讀表可充電電池供電,，長0.17米；

探針安裝桿（LN01）：1.5米,；

手持式讀表（CUR01）：LCD顯示,，數(shù)據(jù)可通過RS232接口下載到計算機；

軟件,、充電器,、包裝箱。
