二氧化碳CO2氣體測(cè)毒管126SG CARBON DIOXIDE 0.02-1.4%

簡(jiǎn)要描述:

二氧化碳CO2氣體檢知管126SF Carbon dioxide 126SG CARBON DIOXIDE 0.02-1.4% 二氧化碳CO2氣體測(cè)毒管126SG CARBON DIOXIDE 0.02-1.4%即保證了安全,提高了衛(wèi)生管理水平及勞動(dòng)效率,也簡(jiǎn)化了管理過(guò)程。1985年GASTEC公司的直讀式氣體檢測(cè)管通過(guò)了日本國(guó)家標(biāo)準(zhǔn)JIS的認(rèn)證,作為“檢測(cè)管式氣體檢測(cè)器"的國(guó)家標(biāo)準(zhǔn)頒布使用(JIS K0804)
