The KDWS-24 is a portable, intelligent SF6 micro-water tester designed for precise dew point and moisture measurement. It features a 4.3-inch color touchscreen for real-time data visualization and curve plotting. Equipped with a self-calibrating sensor, it eliminates zero drift and ensures high accuracy. The instrument uses German-made self-locking connectors for leak-proof operation and includes a built-in 4Ah lithium battery for up to 10 hours of portable use. With fast measurement response, low gas consumption (≈2L), and data storage for 250 test sets, it supports USB data transfer and thermal printing, making it a comprehensive solution for field and laboratory moisture analysis.

• Automatic self-calibration of sensor zero point eliminates system errors and eliminates annual calibration needs.
• Lightweight and compact design (5kg) for easy portability and field deployment.
• Instant-on measurement capability provides results immediately after power-up without warm-up time.
• Low gas consumption of approximately 2L (at 101.2kPa) per test, reducing operational costs.
• German-made self-locking connectors ensure safe, reliable, and leak-free gas connections.
