It can also be used in situations where it is simply not convenient to make a cable connection to a
Windows PC. Suppose for example you are storing some vaccines or chemicals in some environmental
chamber and would like to ensure temperature and humidity conditions are kept within acceptable levels
over time. By mounting a Bluefin logger inside the chamber then one can periodically come near to the
chamber, connect to the logger from an iPhone, download the most recent data, email the recorded data
and configure the logger to continue logging. This can happen wirelessly and without opening the
chamber and affecting environmental conditions.
The Bluefin logger operates in an ultra low power mode even when logging temperature and humidity
and can still be connected to wirelessly without any physical touching of the logger. The logger can
operate in this fashion for 6 months from a fully charged battery. The rechargeable battery may be
charged either by connection to USB on a computer or using a mains/USB power cable.
The Bluefin offers accurate and repeatable logging for temperature and relative humidity. Temperature is
measured to an accuracy of +0.3
o
C over the range +5
o
C to +60
o
C. Over the full range -20
o
C to +60

the accuracy is +2.0
o
C. Relative humidity is measured to an accuracy of +2.0% over 20% to 80%
humidity range and +3.0% over 0% to 100%. Both temperature and relative humidity are logged at a
user configurable logging rate which can be set in the PC application program or iPhone application.

When you would like to guarantee that conditions are within particular environmental limits then one can
also set operating ranges above or below which light indicators will be activated so that the user can
become aware that the desired environmental conditions have been exceeded.
