Portable Instruments
Easidew Hygrometer
The Universal Moisture Portable
The Easidew Hygrometer has been designed to make
dew-point spot checks down to -60°C dew point, and
online measurements across -100 to +20°C dew point,
as simple as possible. This completely self-contained
instrument weighs just 4kg and is delivered ready to use.
Simply connect your sample gas to the Quick Connect (or
optional Swagelok®) ttings, turn on the instrument and it
will begin to measure/display the dew point of the applied
sample.
Extended Field Use
The Easidew uses a rechargeable NiMH battery pack and is
delivered complete with a universal battery charger that ts
neatly into the instrument lid. It will operate for up to 16
hours on a full charge.
Fully Integrated Sampling System
The Easidew is unique among portable hygrometers. Michell
Instruments has built into the standard design, a complete
sampling system that easily allows you to measure the
dew point of any air or gas line, at up to 2 Mpa (20 barg)
pressure. The two interchangeable inlet/outlet ttings allow
you to choose between dew point measured at atmospheric
or line pressure, by simply swapping the position of the
ttings. An integrated lter housing uses standard lter
cartridges and provides 99.5% protection against particles
down to 0.3µm. Optionally, Swagelok® tube couplings can
be specied to allow operation of the unit at up to 30 Mpa
(300 barg).
Measurement Performance
Field Replaceable Integral Sensor
The ceramic metal-oxide moisture-sensing technology is
coupled with the latest microprocessor-based measurement
circuitry to produce a 13-point traceable calibrated and
interchangeable sensor transmitter module. All calibration
data is stored in the sensor memory, so on-site sensor
exchange for calibration or service can be performed quickly,
by untrained personnel.
Easy to Read
The hygrometer features an extremely clear and bright
0.5” red LED display, making it easy to determine the
dew point of your process even in dim conditions or direct
sunlight. Michell also provides a 4–20 mA analog output
for connection to a chart recorder, data-logger or computer
system, so dew-point trends can be analyzed over time.
Rugged Field-Use Design
The Easidew is rugged, and easy to carry and use. It is
small, with an ergonomic carrying handle, and weighs only
4kg. The case of the hygrometer provides NEMA 6 protection
and the outer case is covered by a lifetime guarantee, so can
be returned to the factory for repair or replacement, free
of charge.
Reproducibility and Calibration Integrity
The Easidew ceramic metal-oxide moisture sensors are
subject to a 13-point calibration, where their performance is
characterized against a fundamental reference hygrometer.
This process, and subsequent quality testing, ensures that all
sensors behave optimally before they are used in the eld.
The transmitter uses Michell’s market-leading ceramic
metal-oxide measurement technology coupled with the
latest-generation, sophisticated microcontroller electronics to
provide accurate and stable measurement across the product
life of the transmitter.
• Accuracy ±2 °C dew point
• Excellent long-term stability
Traceable Calibration
Each Easidew is supplied with a calibration traceable to
national standards (NPL & NIST) from Michell Instruments’
accredited laboratory.
Accessories and Spares
The Easidew is available with a supporting range of practical
accessories and spares that can be stored within the lid of
the portable, whilst being used on site:
• Connector ttings
• Filters
• Guards
• Tubing
• Battery pack
• Charger
