新聞中心鹵素水分測(cè)定儀，紅外線水分測(cè)定儀，紅外水分測(cè)量儀根據(jù)各種所需測(cè)定水分的試樣的性質(zhì)，提出了多種水分測(cè)定儀測(cè)定方法，
研究出眾多水分測(cè)定儀器，滿足了我們對(duì)水分定量分析的需求，以下我們將對(duì)幾種常用的水分測(cè)定方法（干燥法）做簡單的對(duì)比分析。
下面是水分儀專家小楊的分析
一、水分是唯yi揮發(fā)性物質(zhì)；
二、樣品中其它成分由于受熱而引起的化學(xué)變化可以忽略不計(jì)；
缺點(diǎn)是精度較低，且不適用于測(cè)液體、氣體、和含揮發(fā)物質(zhì)樣品。
三、不含有結(jié)合水；
鹵素快速水分測(cè)定儀是最近幾年隨著科技的日益進(jìn)步，而快速發(fā)展起來的一種新型水分測(cè)定儀。
該儀器主要應(yīng)用于固體樣品中游離水的含量測(cè)定，
通過高功率的鹵素?zé)艨焖偌訜?，在稱重系統(tǒng)上直接顯示樣品的重量變化，并同時(shí)在水分測(cè)定儀的顯示屏幕自動(dòng)計(jì)算出樣品的水分值。
通過該方法和原理，鹵素快速水分測(cè)定儀也可以測(cè)定某些樣品的揮發(fā)含量或者含固量。
鹵素快速水分測(cè)定儀是由紅外快速水分測(cè)定儀改進(jìn)而來，兩者最主要的區(qū)別是加熱方式不一樣：
鹵素快速水分測(cè)定儀的加熱源是環(huán)狀的鹵素?zé)?，紅外快速水分測(cè)定儀的加熱源是普通的球形的白熾燈泡。
由于加熱燈的結(jié)構(gòu)和原理不一樣，對(duì)樣品的測(cè)試結(jié)果也有一定的影響。
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.
