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.
