Same Quality Product - New Name!
We're building a stronger, unified brand so we can provide you with the best products in the industry. To do this, the Newport branded products will now be Omega branded starting July 15, 2018. You can expect the same support and quality as always, and of course the same features and specs, just with a new part number and logo.
Please refer to iSeries products, CNiTH Controller at omega.com for details.
Starting from Feb 1st 2018, the monitor/meter (00) versions of the iTH series will be discontinued. As a possible substitute, please check out the ITHX-SD Series for details.
The NEWPORT® iTH Series
instruments monitor and control both
temperature and relative humidity. All
meters and controllers in the series
are high quality, highly accurate
instruments featuring Newport's
award-winning iSeries technology,
uncompromising accuracy, backed by
an extended 5-year warranty.
The instruments are simple to
configure and use, while providing
tremendous versatility and a wealth
of powerful features.
The iTH Series instruments
are available either as monitors
or controllers. The monitors are
extremely accurate programmable
digital panel meters displaying
humidity, temperature, or dew
point. The controllers also provide
single output control for humidity
and temperature and are easily
programmed for any control or
alarming requirement from simple
on-off to full autotune PID control.
The iTH family of meters and
controllers are available in four true
DIN sizes: the ultra compact 1/32 DIN;
the popular midsize 1/16 DIN square
bezel with dual display; the 1/8 DIN
vertical, and the 1/8 DIN horizontal with
the big bright 21 mm digits.
The iTH Series LED displays
can be programmed to change color
between GREEN, AMBER, and RED at any setpoint or alarm point.
The iTH controller models offer a
choice of 2 control or alarm outputs
in almost any combination: solid state
relays (SSR); form "C" SPDT (single
pole double throw) relays; pulsed 10
Vdc output for use with an external
SSR; or analog output selectable
for control or retransmission of the
The networking and communications
options (highly recommended)
include direct Ethernet LAN
connectivity with an embedded Web
server, and serial communications.
The C24 serial communications
option includes both RS232 and
RS485. Protocols include both
MODBUS® and a straightforward
ASCII protocol. The C4EIT option
includes both Ethernet and RS485
ASCII/MODBUS on one device.
The iTH Series meters and
controllers are designed for easy
integration with popular industrial
automation, data acquisition and
control programs as well as Microsoft
Visual Basic and Excel. Newport
provides free configuration software
which makes it fast and easy to get up
and running. Available for download
on the Web.

Alarm 1 and 2 (Programmable)
1) Alarms are used for color changing sequence of alarm status (visual alarm).
2) Alarm functions are active, in addition to the color changing functions, if Output 1 & 2 are (menu) disabled.
3) If Alarms are disabled, Output menus (PID or ON/OFF) are active. Color change is still active.
Operation: High/low, above/below, band, latch/unlatch, normally open/normally closed and process/deviation; front panel configurations
-AL Limit Alarm Version: Output 1 & 2 submenus used for PID are eliminated from menu. Color sequence based on alarm setpoints is still available.
