The SL200C temperature logger can be used for a wide range of temperature data logging applications, the company says. Each unit is calibrated to an accuracy of 0.9Â°F (0.5Â°C) over the operating range of -40Â° to 185Â°F (-40Â° to 85Â°C). It is capable of sampling temperature as fast as once per minute or as slow as once every 4 hrs. A total of 2,048 temperature data points can be stored in memory, allowing a logging span as short as 11/2 days or as long as a year, says the company. The unit can also be used to monitor long-term high- and low-temperature alarm events. Sealed Unit Parts Co., Inc.
