USB Temperature and Humidity Data Logger measures and stores up to 16,382 RH and 16,382 temperature readings
Features & Applications:
The user can easily
set up the logging rate and start-time, and download the stored
data by plugging the module straight into a PC's USB port and running
the purpose designed software under Windows 98, 2000 or XP. 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 flashing red
and green LEDs. The logger is protected against ingress from water
and dust to IP67 standard when the plastic cap and seal are fitted.
