產(chǎn)品特點

KH-3000-01A 通過漏砂柱有效收集花粉顆粒，是一款通過前向和側(cè)向的光散射原理花粉數(shù)量的粒子計數(shù)器。光散射法監(jiān)測空氣中花粉數(shù)量。

詳細(xì)介紹

KH-3000-01A 通過漏砂柱有效收集花粉顆粒，是一款通過前向和側(cè)向的光散射原理花粉數(shù)量的粒子計數(shù)器。

KH-3000-01A 與傳統(tǒng)的花粉數(shù)測定方法（如 Cascade、Burkard 等）相比，極大地幫助了研究人員節(jié)省時間，減少了花粉數(shù)量測量的工作量。通過前向和側(cè)向的光散射原理，KH-3000-01 能有效的可靠識別花粉和其他顆粒（例如纖維粉塵）。

通過 RS-232 電纜連接打印機或個人電腦來收集觀測數(shù)據(jù)。在遠(yuǎn)程模式下，可以通過電腦發(fā)出的命令來控制 KH-3000-01A，并且可以方便地將觀測數(shù)據(jù)保存在 PC 機上。
