Temperature, Humidity and Dew Point
Data Logger
Issue 15 01/2020 Page 1 of 4
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 resoluon 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 soware. Data, including calculated dew point, can then be graphed, printed and exported to other applicaons for
detailed analysis.
The data logger is supplied with a lithium metal baery, giving up to three years’ logging life. The logger is protected against ingress
from water and dust to IP67 standard when the cap is ed.
