waterproof temperature humidity data logger - HMHT-LG01

Temperature Logger

This Humidity & Temperature USB data logger measures and stores up to 16,379 relative humidity and 16,379 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 logger and view downloaded data by plugging the module into a PC's USB port and using the supplied software. Relative humidity, temperature and dew point (the temperature at which water vapour 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 up to 1 year.

* This specifies the overall error in the logged readings for relative humidity measurements between 20 and 80%RH.
** This specifies the overall error in the calculated dew point for relative humidity measurements between 40 and 100%RH at 25°C.
*** Depending on sample rate, ambient temperature and use of LCD display.
† At temperatures below -20°C (-4°F) the LCD will exhibit slower response times of approximately 10 seconds

Software

Easy to install and use, the control software runs underWindows 98, 2000, XP (Home and Professional Editions) and Vista (32-bit).
