Temperature and Relative Humidity Logger - SmartReader 2

Smart Reader 2 is a data logger designed for easy and reliable tracking of "air quality" conditions. It has a built-in temperature sensor and a plug-in relative humidity module. The relative humidity module is easily replaceable and interchangeable so you can always be assured of accurate readings.

Applications :

Monitoring office and museum environments, air conditioning and heating equipment, Energy Management systems, and the transportation and storage conditions of perishable goods. SmartReader 2 is supplied with one plug-in RH module. Additional RH modules can be ordered separately.
