The OMEGA® 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 Omega’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 OMEGA 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 4 DIN sizes with NEMA 4X (IP65) splash resistant bezels: the ultra compact 1⁄32 DIN (the world’s smallest dual loop humidity and 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 21 mm (0.83") digits.
The OMEGA 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 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 RS232 and RS485. Protocols include both MODBUS® and a straightforward ASCII protocol. The C4EI 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. OMEGA provides free configuration software which makes it fast and easy to get up and running. Available on CD ROM and for download on the Web.
