卤素水份仪是一种新型快速的水分检测仪器。采用环形卤素灯加热,智能化操作。能快速均匀地干燥样品,获得准确的水份测定结果清晰的水份测定信息显示能实现直观、简单、方便地仪器操作。那么水分测定仪结果不太满意?可能造成结果不准确的原因都有哪些?下面跟着小编一起来看看吧。


卤素水分测定仪


1.选择的温度太高或样品氧化。降低干燥温度;

2.选择的干燥时间太短。延长干燥时间或选择合适的关闭模式“每单位时间的重量丧失”;

3.样品没有完全干燥(例如:由于表面结皮)。尝试混合石英沙进行干燥;

4.样品不均匀。例如它们有不同的成分。样品越不平均则需要更多的样品来获得较好重复性的结果;

5.样品沸腾并不断飞溅从而改变温度。请清洗保护玻璃;

6.当保护玻璃污蚀时,加热量不能完全发挥,请清洁保护玻璃;

7.外部环境不稳定(振动等);

8.操作台不稳固。请应用稳固的操作台;

9.温度传感器被污染或损坏,请清洗温度传感器。
