Dew-Point Transmitter
Easidew EA2
Michell Instruments
The Michell Instruments Easidew is a rugged, 2-wire industrial dew-point transmitter designed for accurate, continuous moisture measurement in gases and non-polar liquids.

The Easidew transmitter series provides a reliable and flexible solution for measuring dew point and moisture content in a wide range of industrial applications. Designed for simplicity, these transmitters are easy to install and maintain, featuring a robust 316 stainless steel construction and a high-performance 525 bar process media barrier for maximum safety and integrity.
Advanced Measurement Technology
Utilizing Michell’s market-leading ceramic metal-oxide moisture sensor technology, the Easidew series delivers stable, repeatable, and accurate measurements.
Measurement Range: -110 °C to +20 °C (-166 °F to +68 °F) dew point.
High Accuracy: ±2 °Cdp (±3.6 °Fdp) across the range.
Fast Response: Optimized for rapid response to moisture changes with a T95 response time of 5 minutes (dry to wet).
Flexible Output: Provides a 2-wire loop-powered 4-20 mA output that can be scaled for dew point or ppmV moisture content.
Global Certifications & Versatility
One stocked unit can often be used globally thanks to a broad range of certifications. The Easidew I.S. (Intrinsically Safe) model is certified for use in hazardous areas by ATEX, UKCA, IECEx, and cQPSus. All models are also Canadian pressure vessel approved (CRN).
Key Applications
The Easidew is the universal choice for various industrial environments, including:
Compressed Air: Suitable for Class 1 to Class 6 dryers.
Specialty Gases: Ideal for hydrogen coolant, welding gases, and inert/bulk gases.
Controlled Environments: Used in glove boxes and for monitoring breathing air.
Safety Critical: Oxygen purity and enriched oxygen service (optional cleaning available).
Ease of Maintenance
To ensure minimum process downtime, Michell offers a Service Exchange Program. Customers can receive a guaranteed, reconditioned sensor to replace their installed unit, ensuring zero downtime while maintaining sensor traceability. Every unit also comes with a 13-point calibration certificate traceable to NPL and NIST standards.
