1. Instrument Introduction:

KX-3000A SF6 Micro-Moisture Tester adopts the advanced DRYCAP humidity sensor from Finland's Vaisala company and utilizes embedded microcomputer technology, making it a high-precision intelligent detection instrument. By measuring the moisture content in SF6, it can quickly and accurately identify early internal faults in electrical equipment such as SF6 circuit breakers, transformers, GIS, busbars, bushings, and transformers. It is suitable for industries including power, railway, metallurgy, and petrochemicals.
　　 Mainly applicable for: precise and rapid moisture detection in non-corrosive gases such as SF6, H2, Air, N2, Ne, He, etc. 

2. Function Overview:

KX-3000A SF6 Micro-Moisture Tester provides a simple method for on-site humidity detection. During use, it is connected to a pressurized gas chamber of equipment, allowing the gas to flow through the sensor at a certain rate, and the instrument directly measures the moisture content of the gas.
 All sensors are imported specialized sensors with a long-life design, ensuring measurement accuracy and reproducibility.
