【摘要】氣體稀釋裝置在各類氣體檢測報警器、氣體分析儀上的應(yīng)用越來越廣泛。通過標(biāo)準(zhǔn)氣體和氣體稀釋裝置對同一臺一氧化碳紅外氣體分析儀在選定的校準(zhǔn)點(diǎn)進(jìn)行校準(zhǔn)，結(jié)合示值誤差、示值重復(fù)性等校準(zhǔn)數(shù)據(jù)分析了兩種校準(zhǔn)方式的差異，為相關(guān)計量校準(zhǔn)工作提供參考。

【關(guān)鍵詞】標(biāo)準(zhǔn)氣體；氣體稀釋裝置；比較

Abstract：Gas dilution device is more and more widely used in various types of gas detection alarm and gas analyzer. In this paper，the same carbon monoxide infrared gas analyzer is calibrated at the selected calibration point through standard gas and gas dilution device. Combined with the calibration data such as indication error and indication repeatability，the differences between the two calibration methods are analyzed，which provides a reference for metrological colleagues in practical work in the future.

Key words：standard gas；gas dilution device；comparison

隨著我國工業(yè)化進(jìn)程的不斷深入，我國對環(huán)境保護(hù)投入的力度不斷加強(qiáng)，針對大氣及生產(chǎn)、工作環(huán)境中的氣體進(jìn)行檢測、分析、報警的各類儀器儀表得到了廣泛的應(yīng)用。（剩余2626字）
