氨檢測(cè)管105SA AMMONIA NH3 0.5-10%

簡(jiǎn)要描述:

氨檢測(cè)管105SA AMMONIA NH3 0.5-10%,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)。
