Our new USB Data Loggers are a cost-effective solution for logging temperature and humidity data just about anywhere. With built-in alarm LEDs you'll know before you download that there has been a danger condition. Set the logging interval and the start time from the PC software and it's that easy. There are no cables, cradles, or dongles to keep track of.

  • LCD Display Loggers
    Keep visual track of your data with our new LCD data loggers for temperature and humidity. Their high contrast LCDs show Min, Max and current readings for both parameters. The display can be shut down during the log to extend battery life while allowing the user to periodically view the displayed readings.

    High Accuracy Temperature and Humidity Loggers
    The TW-USB-2+ and TW-USB-2-LCD+ loggers feature high accuracy for temperature, humidity and dewpoint. New! Record critical temperature and humidity data with precision to ±0.6°F (±0.3°C) and ±2% RH.

    Waterproof Applications
    With an IP 67 rating, our TW-USB-2 & TW-USB-2+ loggers are water resistant and can log in the harshest environments. Store up to 16,382 readings at temperatures to 176°F.
