FD-3013 <\/span>環(huán)境γ輻射監(jiān)測儀適用于放射性礦床普查、勘探，放射性方法尋找地下水源，以及環(huán)境監(jiān)測等需要測定放射性強(qiáng)度的場合。<\/span><\/span> <\/p>

主要特點(diǎn)<\/span><\/span><\/b> <\/p>

FD-3013 <\/span>環(huán)境γ輻射監(jiān)測儀采用較大的<\/span>NaI<\/span>（<\/span>Tl<\/span>）晶體，集成放大器件，單片機(jī)控制，液晶顯示，為靈敏、省電、一體化、手杖式的輻射儀。<\/span><\/span> <\/p>

儀器按測量精度要求自動(dòng)變換量程，并有聲響報(bào)警系統(tǒng)，使儀器操作使用更為方便，并兼顧老<\/span>FD-3013<\/span>的適應(yīng)習(xí)慣。<\/span><\/span> <\/p>
