View Temperature and Humidity with a Web Browser
The OMEGA™ iTHX transmitter lets 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 serves active web pages to display real-time
readings, charts of temperature and humidity, 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, there is no need to invest
time and money learning a proprietary software
program to log or chart the data.
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.
Award-Winning Technology
The OMEGA iTHX is simple to install and use, and
features OMEGA's award-winning iServer technology
that requires no special software except a web
browser.
The iTHX 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 the IP address or an easy to remember
name such as "Cleanroom5" or "Server
Room" in any web browser, and the iTHX serves a
web page with the current readings.
Email Alarms
All OMEGA iTHX 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
mobile 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.
Sensor and Calibration
The iTHX transmitters come complete with a
temperature and humidity probe for measurement of
a single location.
OMEGA offers a choice of industrial probes in 50 mm
(with a 90 cm cable) or 127 mm length (with a 3 m cable)
instead of the commercial wand style
probe which is designed for ambient
indoor applications.
It is not necessary to take the iTHX
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 probes
with optional 3-point traceable
calibration certificates.
Typical Applications
The OMEGA iTHX is great for
monitoring temperature and humidity
in applications such as: clean rooms,
computer rooms, HVAC systems,
pharmaceutical and food processing
and storage, hospitals, laboratories,
semiconductor labs, electronic
assembly, warehousing, museums,
manufacturing, greenhouses and,
farm animal shelters.
