The OMEGA® iSD environmental monitor provides
Web-based remote surveillance of environmental
conditions in critical HVAC applications such as
computer server rooms, clean rooms, laboratories,
museums, warehouses, or any remote facility.
View and record Temperature, Relative Humidity and
Dew Point over an Ethernet network or the Internet
with no special software—just a Web browser.
Email Alarms
The device can trigger an alarm if temperature or
humidity goes above or below a set point that you
determine. Your alarm can be sent by email to a single
user or to a group distribution list, including text
messages to cell phones and PDA’s.
Physical Threats
The OMEGA iSD includes screw terminals for two
contact closures that work with common alarm
sensors. You can instruct the iSD monitor to send an
alarm if a door is opened, a window is broken, or a fire
sprinkler goes off.
Power Failure
The iSD monitor can trigger an alarm if the AC power
fails. The iSD monitor will continue to collect data for
two days powered by a standard 9 Volt alkaline battery
(included). A failure on the Ethernet network will not
interrupt data recording.
Local Alarms
The OMEGA iSD monitor includes two 1.5 Amp output
relays that are controlled by the alarm conditions you
select. The relays can trigger flashing lights and a
siren for example to alert personnel near the scene.
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, as
well as alarm conditions triggered by contact closures.
The relays can also be programmed to turn off when
conditions return to normal, or programmed to remain
latched and require a manual reset.
View Charts and Graphs on the Web
The OMEGA iSD 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 JAVATM Applet that
records a chart over the LAN or
Internet in real time. With the
OMEGA iSD, there is no need to
invest time and money learning a
proprietary software program to log
or chart the data.
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).
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.
SD Flash Memory Card
The iSD 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 directly on a PC or
MAC with a USB card reader. You
can also download the data
remotely over an  Ethernet network
or the Internet.
Sensor and Calibration
The iSD monitors come complete
with a plug-in temperature and
humidity probe that mounts on the
instrument or separately with the six
foot extension cable (included).
It is not necessary to take the iSD
monitor 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.
Installation and operation of the
OMEGA iSD monitor requires no
special training, tools, or software.
The device connects to any
Ethernet network with standard
cable and plugs and is powered
by any AC outlet supplying 110 to
240 Vac.
Award-Winning Technology
The OMEGA iSD is simple to install
and use, and features OMEGA’s
award-winning iServer technology
that requires no special software
except a Web Browser.
The iSD 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 iSD serves a Web Page
with the current readings.
Typical Applications
The OMEGA iSD 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.
OMEGA iServer products are
designed and manufactured in the
USA.
