The OM-EL-USB-TP-LCD standalone data logger
measures and stores up to 32,510 temperature
readings from the supplied thermistor probe which is
attached via the socket at the base of the unit. The
user can easily set-up the logging rate and start-time,
and download the stored data by plugging the data
logger into a PCs USB port and running the included
Windows software. Data can then be graphed, printed
and exported to other applications.
The data logger features an LCD display and pushbutton
which allows the user to cycle through the
most recent, highest and lowest stored temperature
readings. The data logger is supplied complete with
a long-life lithium battery, which can typically allow
logging for up to 6 months. The OM-EL-USB-TP-LCD
is suitable for a wide variety of applications including
high and low temperature monitoring, transportation,
food processing, building and site monitoring and
Windows software is supplied free of charge with
each data logger. Easy to install and use, the control
software runs under Windows XP, Vista, 7 and 8.
The software is used to set-up the data logger as
well as download, graph and export data to Excel.
The software allows for the following parameters to
be configured: logger name, temperature units (°C,
°F), logging rate (1 sec, 10 sec, 30 sec, 1 min, 5 min,
30 min, 1 hr, 6 hr, 12 hr), high and low alarms, start
mode (immediate, delayed and push-to-start logging),
display mode (display off, on for 30 seconds after
button press, or permanently on) and data rollover
(allows unlimited logging periods by overwriting the
oldest data when the memory is full).
The probe supplied with the OM-EL-USB-TP-LCD
uses a precision thermistor to sense the temperature.
The probe length may be extended by the use of a
suitable extension cable (use twisted pair with high
quality 3.5 mm jack socket/plugs for best results).
Probe Temperature Measurement Range: -40 to 125°C (-40 to 257°F)
Resolution (Internal and Displayed): 0.5°C (1.0°F)
Accuracy (Data Logger Error @ 25°C): ±0.1°C (±0.2°F) typical (does not include thermistor probe error)
Accuracy (Thermistor Probe): See thermistor probe accuracy charts on PDF
Operating Temperature Range (Data Logger): -10 to 40°C (-14 to 104°F)
Memory: 32,510 readings
Memory Wrap Around (Rollover): Yes (software selectable)
Logging Interval: 1 sec, 10 sec, 30 sec, 1 min, 5 min, 30 min, 1 hr, 6 hr, 12 hr
Software: Windows XP/Vista/7 and 8 (32- and 64-bit)
Alarm Thresholds: High/low alarm thresholds for temperature (software selectable)
Start Mode: Immediate, delayed and push-to-start logging (software selectable)
Status Indicators (LEDs): Red and green LEDs. The first LED flashes red to indicate that the OM-EL-USB-TP-LCD is in an alarm condition (logged temperature has exceeded a high or low alarm level). The second LED flashes green to indicate that the OM-EL-USB-TP-LCD is logging normally and is not in an alarm condition.
Power: 1/2 AA, 3.6V lithium battery (included)
