This standalone data logger measures and stores over 16,000 temperature and humidity readings from -35 to +80°C (-31 to +176°F) and 0 to 100%RH range at a resolution of 0.5°C (1°F) and 0.5%RH.

The user can easily set up the logger and view downloaded data by plugging the data logger into a PC’s USB port and using the free
EasyLog 21CFR software. Data, including calculated dew point, can then be graphed, printed and exported to other applications for
detailed analysis. The encrypted data has full audit tracking to comply with the requirements of 21CFR Part 11.

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.

The data logger is supplied with a lithium metal battery, giving up to 2 years’ logging life. The logger is protected against ingress fromwater and dust to IP67 standard when the cap is fitted.
