便攜式土壤熱傳導(dǎo)性測(cè)量?jī)x簡(jiǎn)介

一、用途：

在實(shí)驗(yàn)室或野外快速測(cè)量土壤的熱阻力或熱傳導(dǎo)特性，測(cè)量深度可達(dá)1.5米。

二、原理：

NSSP技術(shù)，探針插入土壤，根據(jù)一定時(shí)間內(nèi)溫度變化狀況來(lái)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(cè)試方法）

三、組成：

NSSP探針（TP09）：由讀表可充電電池供電，長(zhǎng)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(guò)RS232接口下載到計(jì)算機(jī)；

軟件、充電器、包裝箱。
