The OMEGA® iBTHX transmitter let's you monitor and record Barometric Pressure, Temperature, Relative Humidity and Dew Point over an Ethernet network or the Internet with no special software except a Web Browser. The OMEGA iBTHX serves Active Web Pages to display real time readings, display charts of barometric pressure, 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 iBTHX, 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 125°C, and 0 to 100% RH) or within any narrow range such as (20 to 30°C). Barometric Pressure can be displayed in hectopascals (hPa), millimeters of Mercury (mmHg), or inches of Mercury (inHg).

| Award-winning Technology The OMEGA iBTHX is simple to install and use, and features OMEGA's award-winning iServer technology that requires no special software except a Web Browser. The iBTHX 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 iBTHX serves a Web Page with the current readings. Typical Applications The OMEGA iBTHX 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 iBTX-M with Flash Memory and LCD Display The OMEGA model iBTX-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 iBTX-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 pressure, 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 iBTHX 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 iBTX-M comes with a universal 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 iBTX-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. Specifications |
