The Easidew Portable Hygrometer has been designed to make in-field checks of the dew point in air and gases as simple and quick as possible. This totally selfcontained instrument, weighing only 4 kg, is delivered ready to use. Simply connect your sample gas to the Quick Connect fittings, turn on the instrument and it will instantly trend the dew point of the applied sample.
Intelligent and Interchangeable Sensor Technology
The key to Easidew's performance is its sensor technology. Michell's Advanced Ceramic Moisture Sensor is coupled with the latest microprocessor based measurement circuitry to produce a fully calibrated and interchangeable sensor transmitter module.
All calibration data is stored within the memory and so sensor exchange for calibration or service can be effected in seconds, even by untrained personnel.
Furthermore, the Easidew Transmitter module can be used as a standalone dew-point transmitter or coupled with the Easidew On-line Hygrometer display unit to form a fixed location, mains powered hygrometer.
Total flexibility, interchangeability and ease of implementation.
Fully Integrated Sampling System
Easidew is unique amongst portable hygrometers. We have built into the design a complete sampling system that allows you to easily measure the dew point of any air or gas line, clean or dirty, at up to 2 MPa pressure.
A fixed orifice port arrangement allows you to select, simply by reversing inlet and outlet ports, whether to measure at atmospheric or line pressure.
An integrated filter housing, accepting standard fibre filter cartridges, gives 99.5% protection against particles to 0.3 micron. All this comes as standard.
Optionally, Swagelok® couplings can be specified to allow operation of the unit at up to 30 MPa, equivalent to 300 barg.
