OM-PL Series Temperature and Temperature/Humidity Models are in the end of life cycle. As a possible substitute, please check out Newest Released Temperature and Humidity Portable Data Logger OM-HL-SH Series for more advanced features.
The OM-PL Series data loggers are
versatile devices that can be used
for a wide range of logging
applications. Each data logger is
capable of sampling data as fast as
once per second or as slow as once
every 18 hours. The data logger can
stop recording when memory
becomes full, or rollover for
continuous recording. The start of
recording is software selectable to
be immediate, delayed, or initiated
when the datalogger door is closed.
The data loggers can also be used
to monitor high and low alarm
events, that indicate if the recorded
data passed above and/or below the
user selected threshold. The alarm
events are stored separately from
the data samples and are not
affected by data rollover. When the
recorded data passes the high or
the low alarm threshold, the
data logger records the time of the
alarm. When the recorded data
returns to within the acceptable
range, the data logger records the
duration of the alarm. Up to 50 such
alarm events can be recorded. The
datalogger has a visual indication of
an alarm condition without the need
to connect to the computer.
The data loggers have an internal
real time clock/calendar. This real
time clock is used to record the time
stamps for data samples and alarm
events. This real time clock is
independent of your computer clock,
and can be set separately, or set to
match your computer clock. The
data loggers provide a high level of
data security. They have physical
security, where the data access
door is locked, and software
security. It is virtually impossible to
falsify the sample data or alarm
information of the OM-PL Series
dataloggers. The data loggers are
extremely low power. Under normal
operating conditions, a 9 volt
alkaline battery will last from 18
months to 2 years.
OM-PL Series data loggers have
the capacity to store over 10,000
readings. Simply connect the
datalogger to your PC’s serial port
and use the available Windows
software to set up the parameters
for your recording session. Once the
datalogger is set up you can
disconnect it and put it in the field to
record data. The data logger door
can be locked on to prevent
accidental or intentional disruptions
of the recording session. When
recording is completed, reconnect
the data logger to your PC and
download the recorded data using
the Windows software. The
Windows software allows you to
view recorded data in text or
graphical format. Models are
available to record internal
temperature and an external
temperature channel (OM-PLT2),
two external temperature channels
(OM-PLTT), temperature, humidity
and dew point (OM-PLTH),
temperature and pressure
(OM-PLPT), AC current
and voltage (OM-PLCV),
4 to 20 mA (OM-PL420), and
internal temperature and an external
thermocouple input (OM-PLTC).
