The JR-1000 series is the easiest to use temperature data logger available. With its precision calibrated
internal temperature sensor, simply place the logger in the field and leave it to record. Once the desired
information has been recorded, plug the logger into your computer and begin downloading and viewing the
logged data with ACR’s TrendReader® Express software.
