This standalone data logger measures and stores up to 16,382 relativehumidity and 16,382 temperature readings over 0 to 100%RH and -35

to +80°C (-31 to +176°F) measurement ranges. The user can easily set up the logging rate and start-time,

and download the stored data by plugging the data logger into a PC’s USB port and running the purpose designed software under Windows

2000, XP and Vista (32-bit). Relative humidity, temperature and dew point (the temperature at which water vapor present in the air begins to

condense) data can then be graphed, printed and exported to other applications. The data logger is supplied complete with a long-life

lithium battery, which can typically allow logging for a year. Status indication is via ashing red and green LEDs. The logger is protected

against ingress from water and dust to IP67 standard when the plastic cap and seal are tted.

EL-USB-2 Humidity, Temperature and Dew Point USB Data Logger CAUTION Exposure of the internal sensor to chemical vapours such as those produced by some plastics and foamed materials may interfere with the internal sensor and cause inaccurate readings to be logged, therefore ensure that the logger is used in a ventilated area i.e. air exchange is allowed.
