설명The OM-TT01 is a very low cost single channel datalogger for temperature ranges –40 to 40°C (-40 to 104°F) or 0 to 80°C (32 to 176°F) user selectable via internal jumper. Its compact size makes it ideally suited for applications requiring multiple loggers for critical temperature monitoring of products. In addition to a green LED indicating the unit’s “active” status, the datalogger also features programmable alarm limits. If an alarm condition occurs, the integral red LED will flash indicating to the observer that the datalogger has experienced temperature conditions outside the pre-set parameters. Once collected, the stored temperature readings (up to 2000) may be downloaded to a computer through the RS-232 cable interface using the Windows software. Downloaded data may then be stored or transferred in a file format which is compatible with most spread-sheet packages including Excel.
