Michell Instruments Easidew Advanced Online dewpoint hygrometer

Click2Contact

The Easidew Advanced Online dewpoint hygrometer from Michell Instruments measures dewpoint, moisture content and now also pressure. Developed as a versatile, high-performance hygrometer system, it features an easy-to-use touch screen interface for set-up and operation. Incorporating the latest Michell ceramic metal-oxide technology, the hygrometer is designed to provide stable and repeatable trace moisture measurements.

Because pressure is such an important variable when measuring the dewpoint of a gas, the hygrometer compensates for this either with a live pressure sensor input or by using a fixed pressure input value. The device can be used for any moisture measurement application, displaying data in °C or °F dewpoint, ppm_V, lb/mmscf or g/m³ from -110 up to +20°C at pressures up to 450 bar. Additionally, the hygrometer also provides analog, digital and four user-configurable alarm outputs. As well as the four-colour display, the hygrometer can be configured remotely via application software.

Regular maintenance and recalibration are important for ongoing reliability and Michell customers have two options to achieve this with minimum disruption. The sensor exchange program is designed to eliminate process downtime: customers order a reconditioned sensor and, when this arrives, replace and return their old sensor. Where traceability of calibration is needed, the company offers a recalibration service at one of its regional calibration laboratories.

The 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, membrane and adsorption dryers, and many more.
