YNYWS-H Insulating Oil Trace Moisture Tester is a newly developed trace moisture measurement and analysis instrument. The instrument uses a high-resolution color touch LCD display, which is convenient, intuitive and easy to operate. The instrument uses a high-performance ARM processor with large data storage capacity, fast and stable operation and excellent anti-interference performance. It has the outstanding advantages of fast detection speed and high accuracy. The instrument has a fault self-diagnosis function. When the test is over, the measurement result will be displayed and printed. The instrument has the function of measuring potential dynamic curve indication, which makes the test state more intuitive; the instrument has a large data storage capacity and can store 1000 data records; the instrument has a delay measurement function, which is very effective when testing samples with lower moisture content; the instrument uses Sliding touch control stirring speed; the moisture content calculation formula includes a variety of calculations based on key parameters such as volume and weight; during the test, if the relevant parameters of the calculation formula need to be modified, it can be modified in time without affecting the moisture determination results. The moisture content is calculated according to the newly revised parameters, which is convenient for users.

The instrument adopts Karl Fischer coulometric titration method, which can reliably determine trace moisture in liquid, gas, and solid samples. When testing, for solids that are insoluble in reagents and substances that easily pollute the electrode and reagent reaction, it can be equipped with corresponding solid, gas, and liquid samplers for indirect measurement. It is a fully automatic analysis instrument. It is widely used in electric power, petroleum, chemical, pharmaceutical, railway, scientific research institutions and other industries.
