1. Instrument Introduction:

KX-3000C Precision Dew Point Meter adopts advanced DRYCAP humidity sensors from Vaisala of Finland and utilizes embedded microcomputer technology, making it a high-precision intelligent detection instrument. By measuring the moisture content in SF6 gas, 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.

KX-3000C Precision Dew Point Meter is primarily used for precise and rapid moisture detection in non-corrosive gases such as SF6, H2, Air, N2, Ne, and He. 

2. Function Overview:

KX-3000C Precision Dew Point Meter 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. 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 repeatability.
