Data loggers - perfect freezer alarms
Data loggers are devices that sample temperature and/or humidity
at regular intervals and then store the obtained information.
Chart recorders used paper and pencil as a storage method, but
they have been replaced by data loggers, which send the
information they gather directly to a computer.
Data loggers were originally created as weather forecasting
tools, but they were quickly adopted as perfect freezer alarms.
Keeping stable temperature in a freezer is much more important
than most people think. It is especially true when we store deep
frozen food there. The 10-degree difference in temperature might
seem small, but it is crucial for items such as deep frozen
products. Only freezer alarms can tell you that something's gone
wrong with your freezer.
Freezer alarms are absolutely necessary in professional
freezers. The standard thermometer inside the freezer shows you
only the present temperature and gradually becomes inaccurate
over time. You need data loggers to check if there were any
temperature fluctuations when no one was looking.
There is one big problem with data loggers that limits its
usefulness. They aren't independent. They need a computer to see
what they recorded. Fortunately there is a data logger that does
not have this problem: ThermaViewer.
ThermaViewer
Unlike other data loggers, ThermaViewer works all by itself. It
has a processor, its own memory and a big LCD screen, it doesn't
need any other device to compute and show all the data it
gathers. Its two sensors can be placed up to 100 feet from one
another, which allows it to monitor and document temperatures,
even in large freezers. All of the temperature history for the
freezers is stored in the ThermaViewer's internal memory and is
displayed as a chart on the LCD screen where ever employee will
be aware of it. This makes every employee part of your quality
control.
