Lascar Electronics EL-USB-2 Humidity, Temperature and Dew Point USB Data Logger EL-USB-2 データシート
製品コード
EL-USB-2
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 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.
