| 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.
NEW 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.
NEW 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.
Connect an External Probe
Connect any type K thermocouple to our TW-USB-TC or TW-USB-TC-LCD loggers and record temperatures to 2000°F depending on the probe selected. Log temperatures in ovens, freezers, and industrial equipment with one of our high temperature thermocouples.
Log in Real-Time
Select our TW-USB-RT and measure temperature directly to your PC in real time. Store up to seven days of data with user-programmable alarm thresholds for both temperature and humidity. The Windows software can send email and text alerts and alert audibly via the PC’s internal speaker.
Waterproof Applications
With an IP 67 rating, our TW-USB-1, TW-USB-1-PRO, TW-USB-2, and 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.
