Real Time Data Monitor for Temperature, Humidity and Dew Point with Direct USB Connection

When plugged into the USB port of a PC installed with the purpose designed software under Windows 2000, XP, Vista & 7, EL-USB-RT measures temperature and relative humidity from -20 to +70°C (-4 to +158°F) and 0 to 100%RH. The PC displays the temperature, humidity and dew point (the temperature at which water vapor present in the air begins to condense) in real-time and saves it to a file which can store up to 7 day’s worth of data. This data file is overwritten at the beginning of each new logging session. The software provides the option for the user to save the data file permanently to the hard-drive. Temperature, relative humidity and dew point can be graphed, printed and exported to other applications.

Windows Control Software

Easy to install and use, the control software runs under Windows 2000, XP, Vista & 7. It provides an environment where the user can view the current temperature and humidity and graph either the current data file or previously saved files. The software can also show the current temperature and humidity in the notification area within the Windows tool-bar. Right-clicking on the EL-USB-RT icon in the notification area enables the user to access the full functionality of the software. Users can set up high and low alarms within the software which can send emails, text alerts or audible alarms via the PC’s internal speaker.

The software allows the following parameters to be configured:

  • °C, °F
  • High and low alarms for temperature and humidity
  • E-mail alert / data set settings
  • Text message alert settings
  • Mute PC’s alarm beep
  • Show readings / icon in notification bar
