REXON EE360 Online Mositure Tester

REXON EE360 Online Oil Moisture Tester is a high-end monitoring device specifically engineered for continuous and reliable measurement of moisture in lubrication oil, hydraulic oil, insulation oil, and diesel fuel. By combining advanced thin-film humidity sensing technology with precision temperature measurement, the EE360 provides highly accurate water activity (aw) values and automatically calculates absolute water content (ppm). This dual-parameter monitoring enables users to clearly understand both the saturation level and actual moisture quantity in oil, offering a comprehensive assessment of oil condition. With its robust sensing probe capable of operating under extreme conditions up to 180°C and 20 bar pressure, the EE360 ensures stable and long-term performance even in demanding industrial environments such as power plants, manufacturing systems, and heavy machinery applications.

Designed for both performance and usability, the EE360 features a durable IP65/NEMA 4 enclosure available in polycarbonate or stainless steel, ensuring excellent protection and easy installation. The device is equipped with a 3.5-inch TFT color display that can simultaneously show up to four parameters, along with powerful data logging capabilities storing up to 20,000 records per variable. Multiple output options—including analog signals, RS485 (Modbus RTU), and Ethernet (Modbus TCP)—allow seamless integration into existing monitoring systems. In addition, users can perform configuration, diagnostics, and firmware updates via intuitive push buttons or dedicated software through a USB interface. With optional ball valve installation, the probe can be inserted or removed without interrupting system operation, making the EE360 an efficient, intelligent, and maintenance-friendly solution for real-time oil condition monitoring.
