USB-2-LCD Self Contained Temperature/Humidity/Dew Point Data Logger with built-in display

A small and accurate battery powered portable solution for logging temperature, humidity, and dew point at intervals from 10 seconds to 12 hours. Stores all data for download to PC or laptop later. Includes ventilated housing, status LED's, plus software for data export to comma delimited data files (for Excel or databases).

The unit is capable of recording relative humidity from 0 to 100%RH, temperature from -31 to +176°F (-35° to +80°C) and calculating dew point temperature from those two values.

The high contrast LCD can show a variety of temperature and humidity information. At the touch of a button, the user can cycle between the current temperature and humidity, along with the maximum and minimum stored values for temperature and humidity. 

This device is small enough to be included in shipping packages to determine if perishables have sustained out of range temperatures and accurate enough to perform scientific analysis. For applications requiring temperature, only, see our USB-1 model. This model is also available without the LCD display: see the USB-2 model. For mission critical live monitoring via the Internet or your LAN see our TempTrax/TempElert product.

This USB temperature/humidity data logger comes with easy to use software for setup, data logging, and graphing:

Description:
 

This device allows you to monitor temperature fluctuations anywhere with a minimum of fuss. It's a "set and forget" device. When you are ready to get the temperature data it has recorded, simply plug it into the USB port of any PC or laptop. The device is small and lightweight enough to place almost anywhere, and can be included in perishable packaging as proof that the perishables have never exceeded required temperature ranges.

Using the Windows compatible software supplied, the USB-2-LCD can be configured to measure temperatures from -35 to +80°C (-31 to +176°F). User selectable logging intervals from 10 seconds to 12 hours and a memory capacity of more than 16,000 readings (for storage up to 2 years) make this data logger ideal for many temperature dependant industrial and consumer applications. 

The USB-2-LCD features a high contrast LCD and two bi-color LED's. The LCD shows logged temperature and humidity values using seven segment numbers, along with annunciators. The LCD can also show information regarding the logging status.

Simply plug the USB-2-LCD into any available USB socket on a PC for instant download and graphing of logged data. Once the data has been downloaded, the logger can be instantly reconfigured to begin the next application.

The data is saved in comma delimited format with date/time stamps for easy import into other spreadsheet, database, and graphing applications.
