要說明的是,適用於本發明該第一實施例的該本體31的材料或形狀並無特別限制,只要能容置該氣體產生單元32,且不會與該氣體產生單元32反應的材料均可。此外,該本體31因為可設計為用於容置產生當次校正用之校正氣體的氣體產生單元32,因此,該本體31可彈性的選擇較小體積或適用環境的尺寸(例如可選擇適用置放於桌上的小型或可攜式的容器),而可更便於使用。
It should be noted that the material or shape of the
該氣體產生單元32具有一容置於該本體31的該容置空間312的氣體產生溶液321,且該氣體產生溶液321可用以產生一具有預定濃度並可與該氣體感測膜21作用的校正氣體。該校正氣體能經由該校正進氣管33進入該氣體感測器2,該氣體感測器2經由量測該校正氣體,並經計算後得到一可據以校正該氣體感測膜21的校正參數。

Accordingly, when the
此外,要說明的是,於一些實施力中,該氣體產生單元32亦可具有用於令該本體31的容置空間312的溫度保持預設溫度的一定溫裝置,而有益於在不同環境使用時,仍能精確控制產生的氣體濃度。

而當要利用本發明該氣體感測裝置對該氣體感測器2進行校正時,則是將可產生與該氣體感測器2所感測之氣體分子相同之校正氣體的氣體產生溶液321置於該容置空間312,並轉動該閥門5,關閉該檢測進氣管22與該氣體感測器3的通路,令該校正進
氣管33與該氣體感測器2連通,然後將該氣體產生溶液321產生的該校正氣體引入該氣體感測器2,即可利用該氣體感測器2感測該校正氣體並依據感測結果得到一校正參數,而利用該校正參數對該氣體感測器2進行校正。該校正參數可以是利用該氣體感測器2量測該校正氣體的電流變化後再經計算而得到一對應的氣體濃度值,再將該計算而得的該氣體濃度值與該標準校正氣體的濃度進行比對,得到量測偏移值後,而得到該氣體感測器2的校正參數。
When the
參閱圖4,本發明含有校正器的氣體感測裝置的一第二實施例,大致相同於該第一實施例,不同處在於,該第二實施例的該校正器3的該氣體產生單元32還包含一設置於該容置空間312,可用以吸收液體的吸收件322。
Referring to FIG. 4, a second embodiment of the gas sensing device containing a corrector of the present invention is substantially the same as the first embodiment, except that the
具體地說,該吸收件322為選自高吸水性高分子或海棉等能吸收液體並具透氣的材質所構成,且型態可以是以單一個聚集體或是由多個小聚集體所組成,藉由該吸收件322將該氣體產生溶液321吸附,因此,可使該氣體產生溶液321不會任意流動,以避免該本體31傾倒時該氣體產生溶液321溢出的問題,而可更具使用的安全性。當使用該第二實施例的該校正器3時,是令該吸收件322充分吸收該氣體產生溶液321至完全濕潤並將其置放於該容置空間312即可。圖4中該吸收件322是以由多個由海綿塊構成的小聚集體所組成,且該氣體產生溶液321已被該吸收件322吸附為例做說
明,然實際實施時不以此形態為限。
