摘要

目前檢測室內空氣品質之設備除有符合環檢所公告之標準分析儀外，另有商業化直讀儀，這類的直讀儀具有及時分析、體積小便於攜帶、安靜、操作簡單、儀器價格及檢測費便宜等優點。因此本研究利用符合公告檢測方法之標準分析儀對直讀儀進行相對準確度測試查核(Relative Accuracy Test Audit，RATA)，期藉由本研究之相對準確度測試增加直讀儀數據的可信度。
本研究分兩部分，首先是建立直讀儀的校正及相對準確度測試的研究方法，再針對幾種直讀儀套用前述建立之校正方法後，在不同條件下與標準分析儀進行相對準確度測試查核。
由實驗結果得知，直讀儀可利用建立檢量線，經線性迴歸修正後增加數據可信度。當檢測濃度在第二類的「室內空氣品質建議值」50％以上時，CO整體之相對準確度較佳，分別為3.26％及5.40％，CO2次之，最後是O3；在建議值50％以下時，CO相對準確度為4.91％及7.22％，CO2最佳可達5.81％，O3為9.36％。由此可知直讀儀在低濃度時之相對準確度較差。就溫度條件而言，直讀儀在操作條件20℃~25℃時相對準確度較佳。

At present, regarding to the equipments for indoor air quality detect, except for the standard analysis equipment certified by the Environmental Analysis Laboratory, there is other equipment called Commercial Direct Reading Instrument, which has various advantages of timely analysis, easy-carry, quiet, easy operation, cheap price and cheap testing fee. Therefore, this Research makes a Relative Accuracy Test Audit of Commercial Direct Reading Instrument by using certified standard analysis equipment, which we expect to add the confidence level of the data detected by Commercial Direct Reading Instrument.

There are two parts of this research. Firstly is to set up an adjustment method of Commercial Direct Reading Instrument and research method of Relative Accuracy Test Audit. Then use the same adjustment method on other several Commercial Direct Reading Instruments to proceed with the Relative Accuracy Test Audit under different Temperature Environment and use the standard analysis instrument.

From the Test Audit, it can increase the accuracy confidence level of Commercial Direct Reading by setting up the quantity Line and adjusting the Linear Return. When the air concentration is over 50% of Classified II “Indoor Air Quality Reference Regulation”, the overall accuracy of CO is much better, which is 3.26% and 5.40%, then the second is CO2, and the last is O3. When the air concentration is under 50% of Classified II “ Indoor Air Quality Reference Regulation”, The overall accuracy of CO is 4.91% and 7.22%, and CO2 is at 5.81%, and O3 is at 9.36%. Therefore, from this Research, the Relative Accuracy of Commercial Direct Reading Instrument is worse when the air concentration is low. Under the temperature condition, the Relative Accuracy is much better when the temperature is at 20℃~25℃.
