Michell Easidew EA2 Dew-Point Transmitter
Overview
The Michell Easidew EA2 Dew-Point Transmitter is a compact moisture meter that measures both dew point and moisture content, built on Michell’s proven Ceramic Metal-Oxide moisture sensing technology. Covering a measurement range of -110°C to +20°C dew point, the Easidew EA2 is widely regarded across compressed air, industrial gas, and process industries as a dependable, easy-to-install solution for continuous moisture monitoring in both safe and hazardous area installations.
Seven Star LLC supplies the Michell Easidew EA2 as an authorized partner to compressed air system operators, gas producers, and process facilities across Oman and the GCC. Every transmitter shipped through Seven Star LLC is genuine Michell Instruments equipment with a traceable calibration certificate, full manufacturer warranty, and local technical support for installations in Muscat, Sohar, and Salalah.
Measurement and Operating Principle
The Easidew EA2 uses Michell’s Ceramic Metal-Oxide Moisture Sensor, calibrated to international standards and delivered with a traceable calibration certificate. Unlike polymer capacitance sensors, the ceramic metal-oxide sensor responds down to -120°C dew point and operates reliably across a wider range of background gases, making it suitable for demanding industrial gas quality applications where sensor robustness matters as much as accuracy.
Output can be configured to display either dew point (-110°C to +20°C) or moisture content (0 to 3000 ppmV) via a standard 4-20mA, 2-wire loop-powered signal at 12-28VDC supply. Accuracy is ±2°C dew point with 0.5°C dew point repeatability, and response time is 5 minutes to T95 when transitioning from dry to wet conditions, ensuring the transmitter tracks real process moisture changes without excessive lag.
Engineering Design of the Michell Easidew EA2
Constructed with a 316 stainless steel sensor and sample block, the Easidew EA2 is available with 5/8in UNF, 3/4in UNF, or G1/2in process connections and MiniDIN 43650 or M12 electrical connectors, simplifying installation across a wide range of existing piping and cabling standards. Sensor covers are color-coded by process connection thread (black for G1/2in BSP, green for 3/4in UNF, blue for 5/8in UNF) to speed correct identification on receipt.
Intrinsically safe Easidew I.S. and Easidew PRO I.S. variants hold IECEx, cQPSus, ATEX, and UKCA approvals for direct installation in hazardous areas when paired with an appropriate electrical barrier. A sensor exchange program allows a newly calibrated, refurbished transmitter to be swapped in without measurement downtime, with the original unit returned to the factory for recalibration – reducing maintenance cost and eliminating extended sensor-out-of-service periods.

Industrial Applications
The Easidew EA2 is widely deployed across Oman’s compressed air systems (Class 1 to Class 6 dryers), breathing air quality monitoring, industrial gas purity verification, and welding gas quality control, providing continuous, reliable dew-point measurement critical to process quality and equipment protection. Its intrinsically safe variants extend this capability to hazardous-area installations common in Sohar’s petrochemical and gas processing facilities.
As an authorized Michell Instruments partner, Seven Star LLC supports industrial gas, compressed air, and process facilities across Muscat, Sohar, and Salalah with genuine Easidew EA2 transmitters correctly specified for the target process connection and hazardous-area classification. This authorized-partner relationship ensures moisture measurement accuracy is backed by manufacturer warranty and responsive local calibration support.

Why Choose Seven Star LLC for Michell Dew-Point Transmitters
A dew-point transmitter is only as trustworthy as its calibration traceability, and getting the correct measuring range and process connection for your specific gas drying or moisture monitoring application matters more than the headline accuracy figure on a datasheet. Seven Star LLC confirms the correct Easidew EA2 range and process fitting against your actual application before shipment, backed by our authorized Michell Instruments partnership across Oman and the wider GCC. We also support gas processing and compressed air facilities across Sohar and Salalah with recalibration scheduling and traceable certificate management, so moisture measurement points remain defensible for both process control and regulatory documentation purposes over the life of the instrument, and our technical team can advise on sensor exchange planning where continuous operation cannot tolerate downtime for recalibration.
Contact Seven Star LLC today to order the genuine Michell Easidew EA2 Dew-Point Transmitter with full manufacturer warranty, traceable calibration certificate, and expert technical support for moisture measurement projects across Oman and the GCC.
