View Barometric Pressure, Temperature, and Humidity with a Web Browser

The OMEGA™ iBTHX transmitter lets 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 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 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 85°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).

Display and Chart Measurements

The iBTHX transmitter comes complete with a barometric pressure, temperature, and humidity probe for measurement of a single location.

OMEGA™ offers a choice of industrial probes in 5" lengths, and a wand style for ambient indoor applications.

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 it can be password protected.

From within an Ethernet LAN or over the Internet, the user simply types an IP address or an easy-toremember name such as “Cleanroom 5” or “Midwest Server Room” in any Web browser, and the iBTHX serves a Web page with the current readings.

Email Alarms

All OMEGA iBT(H)X models that are on a LAN 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.

Typical Applications

The OMEGA iBTHX is excellent for monitoring temperature and humidity in applications such as: clean rooms, computer rooms, HVAC systems, pharmaceutical/food processing and storage, hospitals, laboratories, semiconductor labs, electronic assembly, warehousing, museums, manufacturing, greenhouses, and farm animal shelters.

NEW iBTX-SD with SD Flash Memory and LCD Display

The OMEGA iBTX-SD with LCD display adds several valuable features to the backlit local display of temperature and barometric pressure.

SD Flash Memory Card
The iBTX-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 “.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 iBTX-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 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.

Battery Backup
The iBTX-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.

Link to Web CAM or IP Camera
If you get a message about an alarm condition, you can quickly click on the link to view the actual scene over the Internet.

Rated 5 out of 5 by from Perfect Fit I purchased this unit to provide environmental data for our wind tunnel.
Date published: 2016-11-18
Rated 5 out of 5 by from Killer Application for Engineering/Scientific These sensors are very good. We have them in all our labs and offices. The output data is utilized with our own custom desktop application. Sensing humidity is also a big plus for us due to the organic sensors we make. The built-in server makes the sensor a powerful tool such that all in the company can use the data as a reference for the ambient environment. Now we cannot live without them...thanks much!

I'm trying to access the "Read Sensor" page of this iServer, but it's saying that Java is required. What version of Java is required to view the data?

Asked by: calvin dang
Hello, thank you for your question. Java 8 will work with this series, but the main thing is you need a browser compatible and most browsers are not supporting it anymore. You should use Explorer or Firefox. A better option is to get a software that doesn't require JAVA like iCONNECT or Omega Enterprise Gateway (OEG).

I am trying to calibrate this unit IBTHX-W SERIAL #18120217, but can not find any program that can help me do so. Could you guide me to the software so I can calibrate it.

Asked by: Nach59
Thank you,for your question. Unfortunately, the device dos not get calibrated , just the probe and it has to be returned to Omega for calibration you cannot calibrate in the field. You have to contact Customer Service at CSERVICE @OMEGA.COM or 1-800-622-2378 for a return.

Hi, The manual requests JRE 1.7. Does this matter?

Asked by: synt
If you are using a browser you will require the latest version of Java. When Java is not supported then you can use our software Omega Enterprise Gateway instead.

OMega iserver iTHX-SD 16030519 How often does this unit need calibrtation and is it just the probes and not the monitor? Do you have any calibration instructions?

Asked by: Flo King
Thank you for your question. We recommend annual calibration, but if it is still accurate it is up to the end-user if this is required. The probe is the item that is calibrated and it cannot be done in the field. Most customers just purchase a calibrated probe.

Can we connect this device with local network and read the measurements using LabView program?

Asked by: Sadeq
Thank you for your question. Unfortunately, there is no LabVIEW support for this device.

Does this data logger uses a web interface that rely on Java? Is it compatible with recent web browsers?

Asked by: Prodigy
If you want to communicate with this device directly to its IP address on a web browser, it will require the latest version of Java in order to view the graphs. You can also use our Omega Enterprise Gateway software to monitor and record the data off of the device, which would not require Java.
