Choosing the best product from
this catalog
In this catalog we offer a wide range of products for a
large number of applications. In order to help you fi nd
the correct product we have grouped the products in
two ways: with product names and colored application
groups.
The structure of the product names are as follows:
PC – probe with a connector to the cable
PF – probe with a fi xed cable
RM – room monitoring
WM – wall mount
DT – duct mount
WR – wall-mount transmitter with remote probe on a
cable
DM – for direct measurement with a hand meter
H – capacitive humidity sensors
I – interchangeable sensor module (Hygrosmart)
SF – dew-point instrument based on capacitive sensor
technology
Easidew – dew-point instruments based on ceramic
sensor technology, for low dew points.
Colored application groups
The six color levels you will fi nd as a label on each
product are based on application structure. For example,
complex or accurate applications can be named as
precision manufacturing - this group of applications often
has demands for precise measurement instruments.
Greenhouses, indoor swimming pools and storage of
pharmaceutical products are controlled environments.
Storage of paper, building automation and humidity
control in museums is included in the HVAC category.
The colors used in this catalog can be used as a guide
for choosing the most suitable instrument for your
application.

Product Guide
Chemical tolerance
When moisture levels need to be measured in a gas (or
in air), changes in temperature, the composition of the
gas and the humidity level will all infl uence the stability
of the measurement. In some cases the gas needs
to be analyzed prior to selection of the right product.
Michell’s H-type capacitive humidity sensors have a
long track record of good performance in various types
of contaminated atmosphere. If you are unsure about
your gas composition, we recommend that you contact
your sales representative or Michell application engineer
to verify the application with our extensive chemical
tolerance database.
Interchangeable module
A number of products within our product range offer
a unique interchangeable module, the I7000. Thanks
to this concept there is no need to recalibrate your
instrument. Simply replace the module for a factory
calibrated module. The plug-and-play system guarantees
fast replacement with a short down-time and no
maintenance. Products presented in this catalog that are
equipped with this interchangeable module, are marked
with the interchangeable module symbol.

Interchangeable probe
In order to achieve better specifi cations, Michell
Instruments has designed some of their products for use
with an interchangeable probe. This interchangeable
probe is resistant to temperatures of up to 200°C. As
with the interchangeable module, the interchangeable
probe has a plug-and-play system that guarantees fast
replacement with almost no down-time or maintenance.
The interchangeable probe can be sent back to the
factory for servicing. Products presented in this catalog
that are equipped with this interchangeable probe, are
marked with the interchangeable probe symbol.
