Omnimark Instrument Mark3模块化的水份测定设备用于样品量极大的生产检验。Mark3是根据失重法(Loss On Drying)的测试原理。它主要由两个模块组成,加热和控制模块。加热模块利用红外线石英管加热,使样品均匀地快速受热。控制模块更可同时连接四组加热模块,同时检定四个相同或不同样品,增加检定效率。每个模块可以设定不同的测量参数。在设置菜单中存储的表格可以控制哪个用户可以使用哪个模块,防止从其他人的模块测量引起的混淆,确保测量的可追溯性。 | |
另外,Mark 3特别适合用于塑料行业,它在塑料行业的优势(主要与卡氏法水分仪比较): | |
加热失重法原理,检测无需试剂,无后期费用 | |
检测时无释放有毒气体,更环保 | |
样品无需预处理,操作简便,既能用在实验室也能用在车间现场 | |
标准ASTM6980(该标准专门针对塑料水分检测的) | |
