三 特點
Ø 直接算出葉綠素含量mg/m2;
Ø 測量結(jié)果可靠，不受葉片或樣品大小、厚度和形狀的影響；
Ø 經(jīng)濟、輕便、手持式設(shè)計，適合野外使用；
Ø 與化學(xué)測量結(jié)果高度相關(guān)，即使在高葉綠素含量時；
Ø 彩色觸摸屏顯示；
Ø 離散的單點測量和多點(2-30個樣品)平均值測量模式；
Ø 非易失性閃存（2GB）；
USB數(shù)據(jù)輸出，可使用Excel打開； |
|
四 組成
主機、光纖樣品夾、電池充電器、4節(jié)AA鎳氫充電電池、USB通訊纜線、使用手冊。
可選配件:
20mm大探頭: 增加測量面積。 較大的樣本量可能對某些類型的樣本有用，例如苔蘚

Ø 測量參數(shù)：葉綠素?zé)晒獗嚷?/span>——發(fā)射熒光在735nm/700nm的比值（CFR），或相對葉綠素含量mg· m-2；
Ø 測量面積：直徑3mm的圓，外徑4mm，但對直徑小于3mm的樣品也可準(zhǔn)確可靠的測量；
Ø 分辨率：比值0.01或1 mg· m-2；
Ø 重復(fù)性：依賴于信號強度，對信號強度低的樣品，建議使用多點測量的平均值，對信號強度高的樣品，差異通常為±0.03或更低；。

Ø 檢測：數(shù)控調(diào)制光，將背景光影響將至低。并對光源和檢測器進(jìn)行溫度補償；
Ø 存儲容量：2GB；
Ø 模式：單點測量，2~30個點去平均值，去除2σ區(qū)間外的平均值，或者中位數(shù)；
Ø 樣品接口：光纖傳感器，直徑4mm；
Ø 用戶界面：240 × 320 像素彩色觸摸屏；
Ø 輸出：USB 1.1；
Ø 溫度范圍：0~50 ℃；
Ø 電源：2節(jié)充電AA電池；
Ø 自動關(guān)閉間隔：（無按鍵或下載）0~20分鐘可選；
Ø 大?。?/span>12 cm × 9 cm × 3 cm；
Ø 重量：0.16lbs 275g；
Ø 測量時間：5秒；
