Tempurity System Specifications

• For ultracolds and cryofreezers the preferred method of temperature measurement is through direct connection/communication with the monitored device.  In these cases Tempurity obtains temperatures through data communication rather than through the insertion of a "second" sensor and accuracy is dependent on the monitored device's sensors.
   
• The Tempurity System utilizes advanced digital temperature probes based on the Dallas/Maxim DS18b20Z integrated circuit. This sensor chip reports to .1 degrees C and has a distribution of accuracies based on the temperature. The chip is the most accurate (about .1 degrees C)  at 37C, physiological temperature,  and the least accurate (about 3 degrees C) at -80C. 

• The system collects and stores data from each monitored device by default at 1-minute intervals.

   
• Temperature measurement is asynchronous. Measurements from each monitored device are collected on an independent time schedule.

• There are two alarm levels for which alarm notifications (text message and e-mail) can be defined.
   
• Alarm notification addresses can be defined independently for each alarm level.
   
• Alarm notification addresses can be defined independently for each monitored device.
   
• Every out-of-temperature instance is recorded.
   
• Alarm time thresholds can be defined independently for each monitored device.

• The Tempurity Monitor client can display temperatures in Celsius or in Fahrenheit scale. Celsius is used as the default.

Data retention

• There is no capability for data deletion through the Tempurity System.

Operating system

• The Tempurity Server runs under Windows 2003 Server, Windows XP, or Small Business Server operating systems.  The Tempurity Monitor runs under the Windows XP or Small Business Server operating systems.
