View Temperature + Humidity with a Web Browser
The OMEGA® iTHX-SD 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 OMEGA® iTHX-SD serves Active Web Pages to display real time readings,
display 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 JAVATM Applet that records a chart over the LAN or
Internet in real time. With the OMEGA® 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
The iTHX-SD model 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
“.txt” 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 OMEGA® iTHX-SD features two 1.5 Amp relays. With the easy Web-based setup page, the two relays can be
programmed for any 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 OMEGA® iTHX-SD comes with a universal 100 to 240 Vac 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
The JAVA™ Applet chart scales are fully adjustable on the fly. For example,
the chart can display 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
[-40 to 257°F], and 0 to 100% RH) or within any narrow range such
as 20 to 30°C (68 to 86°F).
Award-Winning Technology
The OMEGA® iTHX-SD 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-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 "Cleanroom 5" or "Server Room"
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.
Sensor and Calibration
The iTHX-SD comes complete with a plug-in temperature and humidity probe that mounts on the instrument or an industrial temperature and humidity probe on a 3m (10') cable. 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.
Installation and operation of the OMEGA iTHX-SD requires no special training, tools, or software. The device connects to any Ethernet network with standard cable and plugs and is powered by any AC outlet supplying 110 to 240 VAC.
Typical Applications
The OMEGA® 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.
OMEGA iServer products are designed and manufactured in the U.S.A.
