Omega Engineering's iTHX-SD-5D Datalogger
iTHX-SD-5D datalogger records temperature, relative humidity and dew point over an Ethernet network or the internet, and locally on an SD card. The new dual channel feature allows for measurement of data from two locations. The device can trigger an alarm if the temperature or humidity goes above or below a set point that the user determines. The alarms can be sent by email to a single user or to a group distribution list, including text messages to cell phones and PDA's.
