The TempElertUSB was designed with these general applications in mind:

  • A mission critical sever room temperature monitor to alert system operators of catastrophic air conditioner failure

  • A monitor for food service programs to warn of potentially spoiled food if the temperature gets above freezing/compliance levels

  • A humidity alert system to warn of water, mildew, and dry/moist conditions that may affect your investment

  • A logging thermometer and hygrometer to provide proof of data in these applications

  • An inexpensive and easy to use device that requires minimal setup, essentially zero maintenance, and offers flexibility in reporting and logging

As far as specific applications go, TempElertUSB can be used for:

Information Tech

Food Services


Other applications

Server room monitoring Freezer overtemp alarm Process control alarm Air temperature logging
Ambient temp monitor Refrigerator alarm Process humidity alarm Greenhouse monitoring
Ambient humidity monitor Humidity alarm Process temperature alarm Wine cellar monitor
Rack space airflow check Temperature logging Warehouse monitoring Vacation home monitor
A/C airstream monitor Humidity logging Air flow alarm Animal barns

The TempElertUSB can be installed on most any computer running Windows 2000 or later, and can be set to monitor the air temperature and relative humidity (plus derived dewpoint) for that location. Even better, using the cabling accessories, it can be extended away from the monitoring computer up to 100 meters (300 feet) using CAT5 network cabling.

TempElertUSB can be set to monitor over and under temperature, dewpoint, and humidity alarm conditions, then alert you several ways:

  • Visually on screen

  • Audibly via computer speaker

  • Via Email

  • Via pager

  • Via cellphone

  • Via mailing list server


The applications are limited only by your imagination. At $99, TempElertUSB is a simple, effective, and inexpensive insurance policy when temperature or humidity extremes can damage your investment.
