Michell has developed the Easidew Advanced Online dewpoint hygrometer as a versatile, high-performance hygrometer system. Incorporating the latest ceramic metal-oxide technology, the hygrometer is said to provide stable, reliable and repeatable trace moisture measurements. It also features an easy-to-use touch screen interface for set-up and operation.

Because pressure is such an important variable when measuring the dewpoint of a gas, the hygrometer compensates for this with either a live pressure sensor input or by using a fixed pressure input value. The Easidew Advanced Online can be used for any moisture measurement application, displaying data in °C or F dewpoint, ppmV, lb/mmscf or g/m³ from -110 up to +20°C at pressures up to 450 bar (6627 psi).

Additionally, the hygrometer provides analog, digital and four user-configurable alarm outputs. As well as the 4-colour display, the hygrometer can be configured remotely via application software.

Regular maintenance and recalibration are essential to ensure ongoing reliability and users have two options to achieve this with minimum disruption. The sensor exchange program is designed to eliminate process downtime: users order a guaranteed, reconditioned sensor and, when this arrives, replace and return their old sensor.

Where traceability of calibration is needed, Michell offers a recalibration service at one of its regional calibration laboratories.

The Easidew Advanced Online Hygrometer is suitable for a wide range of trace moisture measurement applications, such as: surgical and medical air; glove boxes; hydrogen refilling stations; pharmaceutical manufacturing; and membrane and adsorption dryers.
