What is a digital data logger?
A digital data logger is a device used to sample temperature
and/or humidity and then store it electronically. It is
primarily used as a temperature monitoring device in large
freezers and/or stores.
In most cases a digital data logger needs a PC to work with
(with notable exception of ThermaViewer, that can work all by
itself).
Important factors
When you decide to buy a digital data logger, you need to think
about a few things first. As there are many data loggers
available, choosing the one that will meet all your expectations
can be a daunting task. Before you go shopping for your digital
data logger you consider the questions below.
How much data do you want to collect?
Are you going to monitor temperature for a few days, or will
this installation be more permanent and collecting temperatures
over months and years?
Where will it be placed?
Placement is a very important consideration when you buy a
digital data logger, as this has a great impact on the digital
data logger properties. For example, if it's going to be used
for temperature monitoring in the freezer, you will need a
digital data logger that uses remote sensors. You surely won't
be opening the freezer all the time only to check the
temperature. On the other hand if you need to monitor the room
temperature, remote sensors will be only a nice add-on.
What do you need it for?
Do you need temperature monitoring as a safety factor that will
turn on the alarm when the temperature is too high or too low?
Is it going to be a helpful, but non-vital gadget in your server
room? Answers to these questions will tell you a lot about which
digital data logger you should buy.
