MICHELL Easidew Pro 2A85-450 DP Tx | High-Precision Ind Moisture Measurement

​1. Product Overview and Core Specifications​

The MICHELL Instruments Easidew Pro 2A85-450 is a high-precision humidity and dew-point transmitter designed for demanding industrial automation environments. It utilizes advanced ceramic-sensor technology to deliver accurate measurements across a wide range of -80°C to +20°C dew point, with ±0.8°C repeatability. The device features a robust IP65-rated aluminum housing, ensuring durability in harsh conditions such as chemical exposure, extreme temperatures, and high humidity. Its 4-20 mA analog output and Modbus RTU compatibility enable seamless integration with PLCs, SCADA systems, or IoT platforms. The transmitter supports automatic calibration via on-board software and complies with international standards like ATEX/IECEx for hazardous area deployment.

​2. Applications and Industry Use Cases​

This model is widely adopted in critical industries requiring precise moisture control, including pharmaceutical manufacturing, food processing, and HVAC systems. In compressed air networks, the 2A85-450 prevents pipeline corrosion by monitoring dew points to ISO 8573-1 Class 4 standards. Its fast response time (<15 seconds T90) makes it ideal for real-time drying process optimization in plastics injection molding or semiconductor production. Additional applications include lithium-battery dry rooms, natural gas dehydration, and aerospace component testing. Users benefit from its minimal drift over time, reducing maintenance intervals and ensuring compliance with GxP and FDA guidelines in regulated sectors.

​3. Technical Advantages and Customization​

The Easidew Pro 2A85-450 distinguishes itself with patented "Auto-Check" diagnostics, which validate sensor health and alert users to contamination risks. Its modular design allows field-replaceable sensor heads and optional display modules with touchscreen interfaces. The device operates on 12-28 VDC power and includes programmable alarms for out-of-spec conditions. MICHELL offers NIST-traceable calibration certificates and customization for specific gas matrices (e.g., nitrogen, CO2-rich environments). With MTBF exceeding 10 years and global technical support, this transmitter is a cost-effective solution for ensuring process efficiency and product quality in Industry 4.0 automation frameworks.
