Additional Feature


The OM-THA2-U is a multi-function unit that monitors temperature, relative humidity and dew point. The OM-THA2-U records data and generates an alarm for any out-of-range conditions. It consists of a base unit with an easy-to-read display and a 4.6 m (15') remote sensor probe.

The alarm function monitors temperature, relative humidity and dew point once every second. If any of the readings reach an alarm threshold, the unit generates an alarm by turning on a beeper and a dry relay contact. The relay can be connected to a telephone dialer, light or bell. The delayed alarm feature can reduce false alarms by ignoring short duration alarm conditions. The unit will also generate an alarm on probe failure.

The logger function records the data into an internal non-volatile memory at a user specified interval. The recording is performed continuously after the unit is turned on. No computer set-up is necessary to start logging, and all logging settings can be viewed or changed through the front panel functions. When the internal memory becomes full the recording rolls over, overwriting the oldest recorded data. Review logged data on a computer using the included Windows software while continuously recording new data.

All the operating settings of the OM-THA2-U can be changed from the front panel without the need for a computer. The two-line display provides an easy-to-read means of viewing or changing settings.

Rated 3 out of 5 by from Needs to be calibrated... Sent out for calibration to a third party because Omega E does not provide cal services for this particular unit. The unit was found out of +/-2% range. At 53.0 %RH read 49.1%RH. At 75.0 %RH read 70%RH.
