Omega Engineering has introduced the Omega iTHX-SD-5D datalogger that records temperature, relative humidity, and dew point over an Ethernet network or the Internet and locally on an SD card.
The 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 PDAs/
The iTHX-SD features a removable 2 GB SD Flash memory card that can store up to seven years of readings taken at 10 sec intervals. The data is recorded on widely available SD flash cards. The format is a simple text file that is imported to spread sheets and other programs. It can be read directly on a PC or MAC with a USB card reader.
