Product Description

The SmartReader Plus 2 data logger is a self-contained data logger than can monitor and record temperature and relative humidity – right out the box.  The on-board RH sensor is temperature compensated, permitting reliable, worry-free RH readings.  For remote sensing of temperature and RH, simply attach ACR’s temperature/RH probe, or for remote temperature sensing, attach up to two thermistor probes.

The data logger has a built-in temperature sensor, a plug-in relative humidity sensor and is equipped with two extra channels to connect either ACR’s temperature/RH probe or thermistor probes. The RH plug-in sensor is field replaceable so you can always be assured of continuous recording.

The SmartReader 2 is excellent for monitoring air quality conditions.


Monitoring the transportation or storage conditions of perishable and/or pharmaceutical goods, tracking “air quality”, assessing the adequacy of ventilation, as well as HVAC system testing and balancing.
