二.　使用說明

1．儀器簡介

WT系列微型比色計（水質(zhì)分析儀）是以發(fā)光二級管作為單色光源，采用微處理器控制的微型光度計，廣泛適用于實驗室及野外的測量工作。儀器中已經(jīng)預(yù)置了常用的水質(zhì)分析指標的測量程序。本儀器具有以下特點：

u           直接顯示待測物的濃度，同時顯示吸光度值。

u           友好的人機界面，漢字菜單能指導(dǎo)用戶操作。

u           內(nèi)建時鐘，能夠記錄測量日期與時間。

u           500組測量數(shù)據(jù)的*保存與自動刷新

儀器采用四節(jié)5號堿性干電池供電。在室內(nèi)測定時，也可使用外接電源供電。
