Trace Moisture Tester (Karl Fischer Coulometric Titration)|XHWS180
The Karl-Fischer coulometric titration method is the most reliable method to measure trace amounts of moisture in different substances. The XHWS180 trace moisture tester has successfully applied this method, using the most advanced automatic control circuit, a 32-bit embedded microprocessor as the main control core, and an embedded mini operating system. This makes the instrument more reliable and easier to use. It has the characteristics of fast analysis speed, simple operation, high precision and strong automation. Widely used in petroleum, chemical industry, electric power, railway, pesticide, medicine, environmental protection and other departments.
Applications & Target Audience: Engineered for petroleum, chemical, electric power, railway, pesticide, medicine, and environmental protection departments that measure trace moisture in transformer oil and other substances in accordance with the GB/T 7600 standard.
