iSD Series

FCC-B

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.

actual size.

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 JAVA™ 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).

Recording Setup

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.

View temperature and humidity

over Ethernet or the Internet.

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.
