FAQ
Q1: What principle does the XHWS180 trace moisture analyzer use?
It adopts the Karl Fischer coulometric titration method based on the GB/T 7600 standard, which is the most reliable method for trace moisture determination. The iodine generated by electrolysis is proportional to the charge according to Faraday's law, and the water content is calculated automatically.
Q2: What is the measuring range and sensitivity?
The measuring range is 1μg~200mg with a sensitivity of 0.1μg H2O. The accuracy is ±3μg for 10μg~1000μg and ≤0.3% at 1mg, ensuring reliable results even for ultra-trace moisture samples.
Q3: Which industries is this moisture tester suitable for?
It is widely used in petroleum, chemical, electric power, railway, pesticide, pharmaceutical and environmental protection departments, such as transformer insulating oil moisture testing, solvent water content analysis and raw material QC.
Q4: How fast is the measurement?
With 0~400mA automatic electrolysis current control, the electrolysis speed can reach up to 2200μg/s, providing fast analysis speed while maintaining high precision and stable, reliable results.
Q5: How are results displayed and recorded?
The instrument features an extra large color touch screen with graph curve analysis for water content trends, 4 built-in calculation formulas with automatic unit conversion, and a micro thermal printer with time records for convenient result searching.
