德国一家化学分析企业——德兰格尔公司开发出测定室内有毒气体含量的仪器,操作简单,成本低廉。 据报道,德国许多宾馆、饭店、企业和家庭对室内空气中可能存在的有毒物质越来越担心。迄今为止,检测甲醛、五氯苯酚和臭氧等化学物质浓度的手段非常复杂,而且成本昂贵。德兰格尔公司开发的这种“生态环境检测仪”可以准确地测定室内空气中这些化学物质的浓度是否超标。该仪器在药店中就可买到,每台约40马克(1美元约合1.7马克),且特别适合非专业人员使用。
German chemical analysis company - DeLongEr company developed to measure indoor toxic gas content of the instrument, simple operation, low cost. It is reported that many German hotels, restaurants, businesses and families are increasingly worried about the toxic substances that may exist in the indoor air. To date, the means of detecting concentrations of chemicals such as formaldehyde, PCP and ozone have been complicated and costly. This “eco-environment detector” developed by Dreger can accurately determine whether the concentration of these chemicals in the indoor air exceeds the standard. The instrument is available in pharmacies at about 40 marks (1 U.S. dollar or 1.7 marks) each and is especially suitable for use by non-professionals.
