Manufactured to stringent standards, the data loggers are 4.3 in. long by 1 in. thick. They feature a wide temperature range, high accuracy and large 8,000 or 32,000 sampling memory. They also offer analysis functionality such as statistics maximum, minimum and average, enabling a quick glance summary of the environment and historical breakdown. Data can be displayed on the small numeric LCD screen or downloaded to PC via the USB 2.0 connector. To further ensure easy global usage, the battery is easily replaceable since it is a standard model used worldwide.

LCD display: When exposed to temperatures below 5°F (-15°C) Liquid Crystal Displays (LCD) lose contrast and their refresh rate slows. This may result in illegible readings shown on the display. The decline of the LCD function does not affect the sensor recording temperature and the correct values are captured.
