Application Areas
Transformer & insulating oil testing - trace moisture analysis for dielectric oil quality control
Petroleum & petrochemical labs - moisture in oils, solvents, and hydrocarbon products
Electric power utilities - oil condition monitoring and preventive maintenance
Pharmaceutical & chemical QC - moisture in raw materials, intermediates, and finished products
Environmental & pesticide labs - trace water in organic liquids and formulations
Research laboratories - fast, accurate moisture determination across diverse liquid matrices
| Functions and Features |
The instrument incorporates a powerful next-generation processor and new peripheral circuits, offering excellent low power consumption. The measuring electrode signal serves as the criterion for determining the endpoint of electrolysis. Its stability and accuracy are key factors affecting measurement precision. Through the use of advanced devices and methods, precise detection of the measuring electrode signal has been achieved. Further understanding of reagent characteristics has led to the development of a new software compensation correction algorithm, which improves measurement accuracy. A Chinese/English character graphic LCD provides an intuitive and user-friendly display interface. |
| Main functions: |
●Adopting high-resolution color 480×272 dot matrix color touchscreen LCD, English man-machine dialog interface; ●The use of switching constant current source electrolysis circuit (patented technology) to reduce the power consumption of the instrument; ● High-precision measurement electrode signal generation and detection circuits make the judgment of the electrolysis end point fast and accurate, and have strong anti-interference ability; ● Two methods are used to correct the measurement results: reagent blanking current compensation and equilibrium point drift compensation; ● Built-in 9 kinds of calculation formulas, which can meet the calculation of moisture content under different measurement conditions; ● One injection can be converted into mg/L, ppm, mg/kg, %, % to reduce the number of measurements and reagent consumption, and the moisture content conversion unit can also be specified; ● Adjustment of samples volume, mass and density adjustment can be carried out during or after the test; ● 9-speed stirring speed adjustment; 9-speed electrolysis gain adjustment; ● Automatic detection and recording of measuring electrode open-circuit fault and short-circuit fault; ● Automatic storage of historical records with time stamps; ● Reserve RS232 and RS485 ports to communicate with the computer |
