The KDWS-24 is a high-precision intelligent SF6 micro-water and dew point tester designed for comprehensive gas analysis. It features automatic zero calibration and curve tracking correction, delivering accurate dew point measurements from -80°C to +20°C with a resolution of 0.05°C. The instrument includes a built-in filter for removing particulates, stainless steel pipelines to prevent contamination, and a rechargeable lithium battery for up to 10 hours of field use. With fast measurement response, low gas consumption (≈2L per test), and data storage for 150 sets, it supports multiple temperature correction methods and intuitive operation, making it a robust solution for SF6 gas quality testing.

• Automatic conversion to 20°C standard values for accurate temperature-pressure compensation.
• Automatic zero-point calibration eliminates system errors from drift and ensures measurement accuracy.
• Curve tracking correction maintains stable readings across varying environmental conditions.
• Large-capacity data storage for up to 150 test records with non-volatile memory.
• Large LCD display shows dew point, micro-water (ppm), temperature, humidity, and battery status.
• Built-in gas filter removes metal fluoride particles, improving measurement precision.
