View Temperature + Humidty with
a Web Browser
The OMEGA® iTHX-SD transmitter
let’s you monitor and record
Temperature, Relative Humidity and
Dew Point over an Ethernet network
or the Internet with no special
software except a Web Browser.
The iTHX-SD serves Active Web
Pages to display real time readings,
display charts of temperature,
humidity, and dew point or log
data in standard data formats
for use in a spreadsheet or data
acquisition program such as Excel
or Visual Basic.
The virtual chart viewed on the web
page is a JAVA™ Applet that records
a chart over the LAN or Internet in
real time. With the iTHX-SD, there
is no need to invest time and money
learning a proprietary software
program to log or chart the data.
SD Flash Memory Card
The iTHX-SD comes complete
with a removable 2 GB SD Flash
Memory card that can store up to
seven years of readings taken at ten
second intervals.
Records on SD Flash Cards
The data is recorded on widely
available SD (Secure Digital) flash
cards. The format is a simple text
file that is easily imported to spread
sheets and other programs. It can
be read on a PC or MAC with a USB
card reader. You can also download
the data remotely over an Ethernet
network or the Internet.
Alarm Relays
The iTHX-SD features
two 1.5 Amp relays.
With the easy
Web-based setup page,
the two relays can be
programmed for an
combination of temperature
or humidity, and high or low
set points. The relays can
also be programmed to remain
latched and require a manual
reset if a limit is exceeded.
Battery Backup
The iTHX-SD comes with a
universal 100 to 240 Vac power
adapter. A standard 9 Volt Alkaline
battery (also included) allows the
device to log data for up to 2 days
without external ac power. A failure
on the Ethernet network will not
interrupt data recording.
Adjustable Charts
Chart scales are fully adjustable on
the fly. For example, the chart can
display one minute, one hour, one
day, one week, one month or one
year. Temperature and humidity can
be charted across the full span
(-40 to 124°C, and 0 to 100% RH) or
within any narrow range such as (20
to 30°C). When a second sensor is
added, users can select a chart that
records channel 1, channel 2 or the
difference of the two channels.
Award-Winning Technology
The iTHX-SD is simple to install and
use, and features OMEGA’s awardwinning iServer technology that

than actual size with
SD card and DB9-Y cable
for dual probe (included).
requires no special software except
a Web Browser.
The iTHX-SD connects to an
Ethernet Network with a standard
RJ45 connector and sends data in
standard TCP/IP packets. It is easily
configured with a simple menu
using a Web Browser and can be
password protected.
From within an Ethernet LAN
or over the Internet, the user
simply types its IP address or an
easy to remember name such as
“Cleanroom5” or “ServerRoom” in
any Web Browser, and the iTHX-SD
serves a Web Page with the current
readings.

Email Alarms
All OMEGA iTHX-SD models that
are on a LAN that is connected to
the Internet can trigger an alarm
that can be sent by email to a user
or a distribution list anywhere in the
world, including text messages to
cell phones and PDA’s.
Link to Web CAM or
IP Camera
The Web page includes a link to
a “Web Cam” or “IP camera” (not
included). If you get a message
about an alarm condition, you can
quickly click on the link to view the
actual scene over the Internet.
Display and Chart
Two Channels
The iTHX-SD transmitters come
complete with a temperature and
humidity probe for measurement of
a single location. With the addition
of a second probe, the iTHX-SD
transmitter can measure and display
temperature, humidity and dew point
in a second location up to ten feet
away.
The transmitter can display and
chart absolute measurements in
both locations, or a differential
measurement between the two
locations. The second probe
requires no change to the basic
iTHX-SD transmitter hardware,
it can be added at the time of
purchase or in the future. OMEGA
offers a choice of industrial
probes in 2 and 5" lengths, and
a wand style for ambient indoor
applications. A simple DB-9 “Y”
connector is available for adding a
second probe.
Sensor and Calibration
It is not necessary to take
the iTHX-SD out of service
for routine calibration. The
temperature/humidity sensors
are interchangeable and can be
replaced for about the same cost as
a typical calibration. OMEGA offers
replacement sensors with optional
3-point NIST traceable calibration
certificates.
Typical Applications
The iTHX-SD is great for
monitoring temperature + humidity
in applications such as: clean
rooms, computer rooms, HVAC
systems, pharmaceutical and food
processing and storage, hospitals,
laboratories, semiconductor fabs,
electronic assembly, warehousing,
museums, manufacturing, greenhouses, farm animal shelters,
and many more.
