The OMEGA ® iTHX 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 OMEGA iTHX 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 OMEGA 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). When a second sensor is added, users can select a chart that records channel 1, channel 2 or the difference of the two channels.
| Display and Chart Two Channels (models iTHX-W and iTHX-2 only) The iTHX transmitters come complete with a temperature and humidity probe for measurement of a single location. With the addition of a second probe, the iTHX transmitter can measure and display humidity, temperature and dew point in a second location up to twenty 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 transmitter hardware, firmware or software. A second probe 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 to model iTHX-W. No connector is required to add a second probe to the DIN rail mounted iTHX-2. (Dual channel measurement is available on model iTHX-W and iTHX-2 only; it is not available on model iTHX-M.)

| 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 its IP address or an easy to remember name such as "Cleanroom 5" or "Midwest Server Room" in any Web Browser, and the iTHX serves a Web Page with the current readings. Typical Applications The OMEGA iTHX 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. |

| NEW iTHX-M with Flash Memory and LCD Display The OMEGA model iTHX-M with LCD display, adds several valuable features in addition to the backlit local display of temperature and humidity. The "MEMORY" model comes complete with a removable 2-MEGABYTE Flash Memory card that can store one full year of readings taken at one-minute intervals (or two months of readings taken at ten second intervals). Up to four years of temperature + humidity readings can be stored on the 8 Mbyte card. With data being recorded in the built-in nonvolatile flash memory, a failure on the Ethernet network will not interrupt the data record. |

Alarm Relays The OMEGA iTHX-M 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. Email Alarms In addition to the mechanical alarm relays, 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 an Internet enabled pager or cell phone. Battery Backup The iTHX-M comes with an ac adapter. A standard 9 Volt Alkaline battery (also included) allows the device to log data for up to 10 days without external ac power. In locations without power or network accessibility, the iTHX-M continues logging data to its flash memory. The stored data can later be downloaded over the Ethernet. OMEGA iServer products are designed and manufactured in the U.S.A.. |
