日本KOMYOKK北川式氨氣檢測(cè)管AMMONIA 0.5-30%No.105SH
日本KOMYOKK北川式氨氣檢測(cè)管AMMONIA 0.5-30%No.105SH，日本KOMYOKK北川式氨氣檢測(cè)管AMMONIA 0.5-30%No.105SH
詳情介紹：
日本KOMYOKK北川式氨氣檢測(cè)管AMMONIA 0.5-30%No.105SH
日本KOMYOKK北川式氨氣檢測(cè)管AMMONIA 0.5-30%No.105SH，日本KOMYOKK北川式氨氣檢測(cè)管AMMONIA 0.5-30%No.105SH，氣體檢測(cè)管是用來(lái)檢測(cè)某種氣體在某一環(huán)境中所含濃度的簡(jiǎn)易檢測(cè)裝置，通過(guò)檢測(cè)劑與被檢測(cè)氣體的反應(yīng)而出現(xiàn)顏色變化，來(lái)表示所測(cè)環(huán)境中的氣體濃度。在不用任何能源、電源的情況下，具有操作簡(jiǎn)單、使用范圍廣、檢測(cè)準(zhǔn)確、即時(shí)性強(qiáng)和經(jīng)濟(jì)的特點(diǎn)。
