What is a
Temperature Logger?
Temperature loggers are like simple probe thermometers, but they
take and remember the readings. The whole time-series of
readings can then be recovered later, usually by using a serial
interface that connects to a PC computer. Generally,
temperature data loggers are portable battery-operated monitors
that take a time-based "history" of sensor data. They
provide a simple yet powerful solution for analysis and
documentation for research, process monitoring, in-transit
monitoring, QC testing, HAACP plans, warehouse monitoring and
laboratory and environmental studies.
What about
Humidity Logging?
This works the same as temperature logging, but incorporates a
humidity sensor. It is important to realize that humidity
loggers are always temperature loggers, as well, since humidity
sensors require accurate measurements of temperature to quantify
humidity. So, every humidity logger is a "dual temperature
and humidity logger". Humidity sensors drift over time
(temperature sensors also, but not as quickly or as severely).
For proper results, humidity loggers should be recalibrated
every six months. We are experts at recalibration.

Using Loggers in
Transit Monitoring
Temperature loggers are becoming the standard for transit
temperature monitoring in the food and drug industries. Loggers
have the advantage of superior accuracy in demanding
applications, and the convenience of digital data storage and
processing.
Logger Accuracy and Transit Monitoring
Typically, you can trust the record of an accurate logger to
±1°F or ±0.5°C under the best of circumstances. It should be
noted that there are many factors that can influence the
temperature as sensed by the logger, such as recorder placement,
packing geometry, outside temperatures and air leaks.
Nonetheless, loggers perform an invaluable service to record
temperatures alongside the product, which is the best method of
obtaining the true temperatures in which the product is being
exposed.
Software
Importance
Most loggers are paired with software of some kind. Some
loggers can be used with online data storage and reporting (this
is important if there are IT limitations on software
installation on corporate workstations or if wide data
availability to multiple users is required). Make sure
that your application takes into consideration the capabilities
of the software that is used with the logger hardware.
Often the software will make your life easier by automating data
analysis or distribution tasks...ask us to point out the
differences.
Starting, Stopping and Marking
One important aspect of data logging in general is the control
of stopping and starting and making "event" marks on a time
based record. Some loggers have a "start button".
Others rely on magnetic activators or starter devices. In
some instances, a logger can be always running, so that they
simply need to be stopped or interrogated when data is needed.
All of these options are possible with the different types of
loggers we sell.
Important Extra Stuff
Many applications are highly technical. Gathering data in
special situations requires a more extensive suite of adaptable
and complementary "parts" to your logging system. Global Sensors
can provide accessories for your logger system: readers, special
probes and application-specific logger options. Please call us
to discuss your specific requirements: 1-866-402-8282 (toll
free) or 1-704-827-4331.
Why is wireless
data gathering important?
Some applications require quick or "unattended" data gathering.
Wireless systems allow the data gathered by the logger to be
remotely reported to a data terminal (a computer or other
device). Wireless data monitoring is very affordable and
offers some real advantages. Global Sensors is a leader in
wireless monitoring for warehouse or retail operations, for
HACCP or supply chain solutions. Please call us to discuss your
specialized application: 1-866-402-8282 (toll free) or

Why is an integral USB logger a big deal?
Many of our customers use loggers to ship to hundreds of
different locations. The recipient returns the logger to
the shipper after reading the recorded data. With so many
locations to ship to, providing all of these locations with
hardware interfaces would not only be too expensive, it has
logistic difficulties. Software is free and universally
available, so having built-in interface capability makes the
logger "hardware free" when it travels to different locations.
