Background

The micro-moisture meter coulomb method is widely applied to measuring the water content in high-moisture substances, and is high in measurement precision and environment-friendly.

However, when the micro-moisture meter coulometry method is used to measure the water content of the chemical fiber oil with high viscosity and high water content in the actual use process, the sampling speed is high when a larger sampling needle is used for sampling, but the sampling amount is large, the actual consumption of the Karl Fischer reagent is increased, the cost is increased, the measuring time is greatly prolonged, and 3-10min is needed. The sensitivity of the electrolyte is reduced due to the fact that the measuring time is prolonged, moisture in the air can interfere with the measuring result, the deviation of the final measuring result is large, the accuracy is not high, the measuring needs to be repeated for 3 times or even more, and reagent consumption and measuring time are further increased.
