The WKT-L-50ZS online microwave liquid moisture analyzer is an intelligent, high-precision industrial instrument for online microwave liquid moisture measurement. Its sensor uses dual-frequency microwave signals, delivering better accuracy than moisture analyzers using single-frequency microwave signals. Made entirely of stainless steel, it is exceptionally rugged and durable, withstanding pressures up to 4 MPa and temperatures up to 120°C. The moisture content range of 0–100% can be freely selected, and high-precision temperature compensation is provided. Using a three-dimensional calibration method, it includes 8 calibration tables for measuring different media. It is widely used for moisture content measurement of various oils, chemical liquids, and food and beverages.

The WKT-L-50ZS is an ideal industrial liquid analysis instrument, widely applicable to moisture content measurement of various oils, chemical liquids, and food and beverages.
The WKT-L-50ZS is insensitive to liquid color and can even measure most weakly conductive media. Microwave measurement is a depth detection technology — microwaves penetrate a certain distance into the measured medium, making it superior to surface detection technologies such as infrared detection.
Built-in temperature measurement and temperature compensation for high-precision measurement;
Real-time measurement with high speed and fast response (less than one second);
The probe is made of stainless steel with PTFE fittings — corrosion-resistant and rust-proof;
No moving parts — low maintenance and long service life
Meets explosion-proof (Ex ia d IIC T6 Ga/Gb) and protection (IP68) ratings for harsh sites;
Adopts dual-frequency microwave detection technology, unaffected by flow state and industrial environment factors;

Structural Diagram of the WKT-L-50ZS Online Microwave Liquid Moisture Analyzer
The WKT-L-50ZS is made entirely of stainless steel; corrosion-resistant materials can be customized for corrosive liquids. It offers excellent pressure resistance (standard type: 1 MPa; high-pressure type: 4 MPa), and high-pressure versions can be customized according to on-site needs (up to 40 MPa). Its temperature resistance reaches 120°C (standard: 80°C; for temperatures above 120°C, please contact us for customization). Rugged and durable, it is an ideal industrial analysis instrument.
The software offers rich functionality: automatically recording and displaying trend curves; real-time display of medium temperature, current moisture value, and average value; remote calibration settings for the instrument; export of moisture measurement data; alarm settings; curve printing; and more.
Using dual-frequency microwave signals and a three-dimensional calibration method with up to 8 calibration tables, its measurement accuracy far exceeds that of ordinary single-frequency microwave moisture analyzers, reaching up to 0.01% — suitable for higher production requirements.
