He says "There are many temperature critical goods which can be
completely ruined by low temperatures. However, some of the damage
that the cold can inflict is not always visible, so we have been
working flat out supplying customers with temperature logging
systems that can raise alarms and provide a 24/7 record of
temperature."Gemini's Tinytag loggers are small, low-cost and
extremely easy to use, which means that they can be quickly placed
in important locations to monitor and protect valuable goods.
Configuration by PC takes just a few seconds and the loggers can
then be left in position to monitor temperature or other parameters
such as humidity.
An enormous variety of goods are affected by the threat of low
temperatures. For example, vaccines must be transported and stored
according to manufacturers' recommended temperature range of +2°C
to +8°C until the point of administration. Any deviation from these
conditions may result in a loss of vaccine potency which would
incur a substantial financial loss.
Fresh goods such as salads, vegetables and horticultural
products are also damaged by low temperatures. However, there are a
large number of products for which the cold or humidity can cause
serious harm but which do not display visible symptoms - these
include pharmaceuticals, foods and food ingredients, and even
fireworks and ammunition.
Several versions of the Tinytag loggers incorporate a red light
which flashes when an alarm condition is reached. However, they can
also be configured to trigger an external alarm.
The latest versions are available with radio telemetry so that live
data from any number of loggers can be displayed on a single PC.
This provides an opportunity for an entire facility to be fitted
with a complete wireless real-time monitoring and alarm
Nigel hopes that many more facilities will take advantage of
logging technology and he says he is "very much looking forward to
being able to issue a similar warning when high temperatures are
the main concern."
