Q: What are the differences between SmartReader and SmartReader Plus data loggers?

A: SmartReader Data Loggers are precise instruments with low resolution for use in applications where the magnitude of the readings is of primary importance and cost may be a factor. Its simple setup makes it uncomplicated and the information collected is very usable considering that most sensors are no better than 1% or 2% accurate. This approach to data logging focuses on the big picture rather than the details that tend to distract. Available in low memory size makes small files that are easy to manipulate.

SmartReader Plus Data Loggers are full featured high resolution precision instruments for applications where detail is important. Their features set includes bused based networking and alarm alert mechanism make them ideal for continuous monitoring. They are available in a wide range of memory sizes including the largest number of readings of any portable self-contained device marketed.
