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 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 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.

Live Readings

from Santa Ana, CA
using the iTHX-SD Temperature & Humidity Ethernet Transmitter

SD Flash Memory Card
The iTHX-SD comes complete with a removable SD Flash Memory card that can store up to 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.

iTHX-SD ET
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 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 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 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 "Cleanroom5" or "ServerRoom" in any Web Browser, and the iTHX-SD serves a Web Page with the current readings.

Email Alarms
All 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.

Previous Omega Model DPiTH Serial RS-232 let us read Humidity through *X01 and Temperature through *X02 queries. Does Telnet interface on ITHX-SD-5 model support same queries or equivalent to read Temp and/or Hum directly through SCPI queries?

Asked by: svaleal
Thank you for your question. The command queries for the ITHX device are different. Please refer to section 4.91 of manual you can download from our website. https://www.omega.com/en-us/iiot-wireless/ithx-sd-series/p/ITHX-SD

The iTHX-D3 used a separate End Character for Temp, Hum and Dew Point. We knew which one was being transmitted to the PLC based on that end character. Now the D3 has been replaced by the SD and it does not allow us to do this. What options do we have now?

Asked by: MikeS
The SD version does not have the option for the end character that is correct. However management has reinstated the D3 unit so you can contact customer service and return the SD model and order a D3 to fit your needs.
