    Abubuwan amfani da firikwensin gas na NDIR:

    1. Anti-guba, babu ajiyar carbon.Lokacin da firikwensin CAT ya auna wasu iskar gas, yana da sauƙi a ajiye carbon saboda ƙarancin konewa, wanda ke haifar da raguwar ma'auni.Ana kiyaye tushen hasken IR da firikwensin gilashin ko tacewa, kuma kar a tuntuɓar gas, don haka ba za a sami konewa ba.

    2. Ba a buƙatar oxygen.NDIR firikwensin gani ne kuma baya buƙatar oxygen.

    3. Ma'auni na aunawa zai iya kaiwa 100% v / v. Domin halayen siginar na NDIR firikwensin sune: lokacin da babu iskar gas da za a auna, ƙarfin siginar shine mafi girma, kuma mafi girman ƙaddamarwa, ƙarami siginar.Don haka auna babban taro ya fi sauƙi fiye da auna ƙananan ƙididdiga.

    4. Kyakkyawan kwanciyar hankali na dogon lokaci da ƙarancin kulawa.Kwanciyar firikwensin NDIR ya dogara da tushen haske.Muddin an zaɓi tushen hasken, kuma ana iya amfani da shi shekaru 2 ba tare da daidaitawa ba

    5. Faɗin zafin jiki.Ana iya amfani da NDIR a cikin kewayon -40 ℃ zuwa 85 ℃
