| 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) | |
