The KDWS-24 is a portable SF6 micro-water and dew point tester designed for precise gas moisture analysis. It features a 4.3-inch color touchscreen that displays real-time dew point, micro-water (ppm), temperature, humidity, and battery status. With automatic zero calibration, it eliminates system errors and ensures measurement accuracy. The instrument uses German-made self-locking connectors for leak-proof operation, has a built-in 4Ah rechargeable battery for up to 10 hours of field use, and supports data storage for 250 test sets, USB data transfer, and thermal printing, making it a comprehensive solution for SF6 gas quality testing.
