A New Range
of Handheld Relative
Humidity Instruments

The range has been specifically
designed in response to demand
for the effective and reliable
measurement of controlled
environments. Featuring 2 models,
RH-202 and RH-202L with the latter
including functions: dew point,
calculation, separate thermocouple
input and logging.

Performance

The RH-202 meters from
OMEGA®offer the user the
highest accuracies for a budget
price. The ergonomic case design
with advanced technology
sensors combine to give an
instrument with excellent
performance and long life.

The RH-202L features an
external temperature probe
option for pinpoint temperature
measurement. 250 readings
can be logged, replayed on the
screen and output to a printer
or PC using the HHP-2000-DL.
Each reading is user coded and
time and date stamped.

Dew Point

The dew point is defined as the
lower temperature to which air must
be cooled in order for condensation
(saturation) to occur. The dew point
is dependent on the concentration
of water vapor present, and,
therefore, the relative humidity.

Simple Data Collection
and Analysis

The RH-202L features special
logging functions that enable
readings to be taken, stored,
retrieved and downloaded in the
shortest possible time. This reduces
the risk of clerical errors and saves
writing and keying-in time when
analysis is needed.

Logging on Demand

Logging on Demand allows
readings to be stored when
required, with the ability to add a
4-digit reference number (including
decimal point) to each reading and
record the date and time each
reading is taken. This function is
excellent for helping you cut down
on paperwork and clerical errors. It
is ideally suited to tasks where you
wish to maintain a record of the time
and date when a temperature was
taken.

Pre-Set Interval Logging

Pre-set interval logging lets you
determine the frequency at which
readings are taken. Once the
instrument has been set, readings
are taken automatically at the
interval you decide (from once every

minute to once every 24 hours),
providing an excellent means of
troubleshooting and examining
trends over a given period of time.
With preset interval logging, you
really can “set it, forget it” as the
instrument will continue logging until
a maximum of 250 readings are
taken or your data is downloaded.

Data Analysis

Data can be viewed and analyzed
direct from the magnified display. By
simply pressing a few keys you can
scroll through your readings with
ease. You may then download the
data to a PC or Epson compatible
printer via OMEGA’s HHP-2000-DL.
Data can then be analyzed using
our OM-MLWIN.

Data Download
with the HHP-2000-DL

Access to stored information is
gained via OMEGA’s infrared
HHP-2000-DL, which is designed
to give users a quick and simple
means of retrieving and
downloading data. Information can
be output direct to either an Epson
compatible printer for immediate
study or downloaded to a PC for
more detailed analysis.

Data Analysis with
OM-MLWIN for Windows

®

OMEGA®has created a Windows
software package enabling
information to be put into
spreadsheets and charts for
incorporating into reports and other
documents. Even separate reports

Minimum PC requirements:

386, 4MB RAM running with either

Windows 3.1X or Windows 95.

from different units can be merged
to produce one report.

PC analysis really couldn’t be any
simpler. By following the software’s
simple menu instructions, you will
find it easy to view and manipulate
information to your individual
requirements. For example, once a
logging session is complete, all you
need to do in order to gain access to
information stored within the
instrument is position the PC’s
cursor over the “Retrieve Data”
menu icon, click once and press a
button on the instrument.
Information is then automatically
transferred, via the infrared link and
stored within the computer.

You may display the retrieved
information in graph format by
positioning the cursor over the
“Display As Graphical Data” menu
icon and click again. You can
access the graph produced to
highlight certain areas or key data
points, prior to printing or exporting
the graph into other software
packages.

Furthermore, all graphs show the
identification number of the
instrument used, enabling data to
be cross-checked against
calibration records helping to ensure
full traceability.
