Measure and record the temperature of the surrounding environment with the Model MTL10 Mini Temperature Data Logger. Each unit is factory calibrated to an accuracy of ±0.9°F (±0.5°C) over the operating range of -40 to 185°F (-40 to 85°C). Model MTL10 can store up to 2048 temperature measurements and can be set for continuous measurement or stop recording when the memory becomes full. Sampling rate is selectable from one minute to once every 4 hours. Recordings can be programmed to begin immediately, delayed (up to 6 weeks), or initiated by a push button. The logger has visual indication of an alarm condition without the need to connect to the computer.
