Contact formThe determination principle of this instrument is the world-recognized classic method for water measurement, the “Karl Fischer Coulometric method”. This method features high testing accuracy and extremely low testing cost. It is the most specific and accurate chemical method and also a globally recognized industry standard analysis method. The liquid can be quickly determined within one minute. Solid. The moisture content in the gas is directly displayed as the measurement result, with a measurement range of 0.0001% (1ppm) to 100%. It is widely used in the petroleum, chemical, power, pharmaceutical, pesticide, railway industries and scientific research units in colleges and universities.
The sample determination process is automatically controlled by the instrument. Stirring and determination are completed automatically within about 60 seconds, and the determination results are directly displayed. The fully enclosed titration system avoids the harm of reagents to the operators. The 500ml Karl Fischer reagent that comes with it can continuously measure about 1000 samples and has other significant advantages. It completely avoids the excessive errors that occur in the process of determining water content by other methods, thereby improving the quality indicators of the product.
