1.精確P50:當(dāng)pH控制在7.40+.01時(shí)精度為+1mmHg，且溫度為37.0°C。

2.樣本容量:可選擇從5到50微升的全血或紅細(xì)胞懸液。

3.繪圖時(shí)間：繪制完全氧離曲線(xiàn)或氧合曲線(xiàn)需要30分鐘或更短。

4.光測(cè)系統(tǒng)：雙源波長(zhǎng)光度計(jì)、分離型光束、雙光電增倍檢測(cè)器、PC-電路板,前控制面板。

5.P02儀:克拉克電極系統(tǒng)可以讀取精度為0.1mmHg的壓力數(shù)據(jù)。

6.GAS-系統(tǒng):多氣體測(cè)量系統(tǒng)，具有用于進(jìn)行氣體選擇的2通式和3通式螺旋形轉(zhuǎn)向閥，可以面板上操作。

7.采樣系統(tǒng):裝有壓力-真空泵，用于樣品填充和比色槽的沖洗，控制鍵位于面板上。

8.溫度控制:電子加熱系統(tǒng)使工作溫度穩(wěn)定在37°C,精確的溫?zé)峥刂葡到y(tǒng),感應(yīng)樣本測(cè)量?jī)x溫度的精確度為0.2°C。InthenewModelDthebloodsample(30to50ul)isaddedtotheHEMOXSolutionorotherbuffercontainedinasampletubefortransferintothecuvette.Thecuvette,whichisanopticalsamplecellcontainingtheoxygenelectrodeandthermistorprobe,ismountedinacuvetteholder.Alsocontainedintheccuvetteisamagneticstirringbarforrapidstirringofthesamplebuffermixture.Thecuvettecontainstwo(2)stoppersonthetop,oneofwhichisusedforsampleintake,whiletheotheronesuppliesvacuumtothecuvettechamber.Aftertheplottingofthecurve,thesampleisremovedthroughthebottomoutletporttodrain.
