产品介绍
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)
  • 准确测量塑料内低至50ppm的水份
  • 减少不必要的干燥时间和电能损耗
  • 减少废品率,提高生产效率
  • 即装即用,一键按式操作
  • 测试结果与国际公认的卡尔费休滴定法(Karl Fischer)的结果相符
  • 测试方法符合ASTM D6980标准
  • 带打印机,可当场打印数据
  • 减少注塑机和干燥机的维护成本
  • 特别适用于塑料行业
