氨氣檢測儀/報警儀測量安全范圍值是多少ppm-深國安官網

氨氣檢測儀/報警儀測量安全范圍值是多少ppm呢?根據中國職業接觸限值(GBZ 2—2002)規定，氨氣時間加權平均容許濃度值(TWA)為20 mg/m3，氨氣短時間接觸容許濃度值(STEL)為30mg/m3。例如氨氣檢測儀量程為0~100ppm,那么它設置的量程一級報警值為25ppm，二級報警值為50ppm，TWA值為25ppm,STEL值為35ppm。注釋：氨氣檢測儀TWA值是指時間加權平均值，以平均一個工作日暴露于有毒氣體累計為基礎的時間加權平均值。另外氨氣檢測儀STEL值是指短期暴露極限值，意思以用戶5-15分鐘時間段為基礎的短時間暴露氣體極限。
