View Barometric Pressure, Temperature, and
Humidity with a Web Browser
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 iBTHX serves Active Web Pages to display real
time readings, display charts of Barometric Pressure,
temperature, humidity, and dew point 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).

Typical Applications
The iBTHX is great for monitoring barometric
pressure, 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,
green-houses, farm animal shelters, and many more.
The iBTHX transmitters come 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 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 iBHTX 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 iBTHX
serves a Web Page with the current readings.
Email Alarms
All OMEGA iBTX 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.
NIST-traceable calibration certificate available.
In compliance with ISO9001:2008, ISO10012-1.1992(E),
ANSI/NCSL Z540-1.1994 and MIL-STD-45662A.

NEW iBTX-SD with SD Flash Memory Card and
LCD Display
The OMEGA model iBTX-SD with LCD display, adds
several valuable features in addition to the backlit
local display of barometric pressure and temperature.
SD Flash Memory Card
The iBTX-SD 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 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.
