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, and Made in the U.S.A.
quality, 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
NEWPORT 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 dual loop control
for both 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 with NEMA 4, IP65 splash resistant bezels:
the ultra compact 1/32 DIN (the world's smallest dual loop Humidity
+ Temperature controller); 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 21mm digits.
The NEWPORT iTH series LED displays can be programmed
to change color between Green,
Amber, and Red
at any set point or alarm point.
The iTH controller models offer a choice of two 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 process value.
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 RS-232 and RS-485. Protocols include both
MODBUS and a straightforward ASCII protocol. The C4EI option
includes both Ethernet and RS-485 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
and data acquisition software and demos which makes it fast
and easy to get up and running with many applications.
