卤素水分测定仪，红外线水分测定仪，红外水分测量仪根据各种所需测定水分的试样的性质，提出了多种水分测定仪测定方法，
研究出众多水分测定仪器，满足了我们对水分定量分析的需求，以下我们将对几种常用的水分测定方法（干燥法）做简单的对比分析。
下面是水分仪专家小杨的分析
一、水分是唯yi挥发性物质；
二、样品中其它成分由于受热而引起的化学变化可以忽略不计；
缺点是精度较低，且不适用于测液体、气体、和含挥发物质样品。
三、不含有结合水；
卤素快速水分测定仪是最近几年随着科技的日益进步，而快速发展起来的一种新型水分测定仪。
该仪器主要应用于固体样品中游离水的含量测定，
通过高功率的卤素灯快速加热，在称重系统上直接显示样品的重量变化，并同时在水分测定仪的显示屏幕自动计算出样品的水分值。
通过该方法和原理，卤素快速水分测定仪也可以测定某些样品的挥发含量或者含固量。
卤素快速水分测定仪是由红外快速水分测定仪改进而来，两者最主要的区别是加热方式不一样：
卤素快速水分测定仪的加热源是环状的卤素灯，红外快速水分测定仪的加热源是普通的球形的白炽灯泡。
由于加热灯的结构和原理不一样，对样品的测试结果也有一定的影响。
According to the properties of various samples needed to measure water, a variety of methods for the determination of water content are proposed.
A number of water measurement instruments have been developed to meet our needs for quantitative analysis of water. Below, we will make a simple comparative analysis of several commonly used water measurement methods (drying method).
The following is the analysis of moisture meter expert xiao Yang
Water is the only volatile substance;
2. The chemical changes of other components in the sample caused by heating can be ignored;
The disadvantage is that the accuracy is low, and it is not suitable for the measurement of liquid, gas, and volatile substance samples.
3. No combined water;
Halogen rapid water meter is a new type of water meter developed rapidly with the progress of science and technology in recent years.
This instrument is mainly used for the determination of free water in solid samples.
Through the quick heating of the high-power halogen lamp, the weight change of the sample is directly displayed on the weighing system, and the moisture value of the sample is automatically calculated on the display screen of the moisture meter.
By means of this method and principle, the halogen rapid moisture meter can also determine the volatile content or solid content of some samples.
The halogen rapid moisture meter is improved from the infrared rapid moisture meter. The main difference between the two is the heating method:
The heating source of halogen rapid moisture meter is ring halogen lamp, and the heating source of infrared rapid moisture meter is common spherical incandescent bulb.
Due to the different structure and principle of the heating lamp, the test results of the sample are also affected.
