W300 Online Liquid Moisture Analyzer

The newly upgraded W300 Online Liquid Moisture Analyzer from COLIY incorporates the company’s patented dual-antenna microwave sensor, enabling precise moisture detection across a full 0–100% range—even in slightly acidic, alkaline, or other high-conductivity environments. The device features expensive perfluoroelastomer sealing rings, offering exceptional corrosion resistance and anti-aging properties to ensure long-term reliability.

The W300 is an intelligent, high-precision industrial moisture analyzer designed for liquids. Its dual-frequency microwave technology delivers superior accuracy compared to single-frequency sensors. Constructed entirely from stainless steel, the W300 is rugged, durable, and withstands pressures up to 4MPa and temperatures up to 120°C. Users can select any moisture range within 0–100%, supported by high-precision temperature compensation and a 3D calibration method with 8 preset calibration tables for diverse media.

Ideal for industrial applications, the W300 is widely used to measure moisture in oils, chemical liquids, and food/beverage products. It is insensitive to liquid color and can even measure weakly conductive media. Unlike surface-level techniques (e.g., infrared), its microwave-based depth detection penetrates the medium for more accurate results.

The W300 is CE-certified and explosion-proof certified.
