SmartReader Plus 4
Four-Channel Pressure, Temperature and Relative
Humidity Data Logger
The SmartReader Plus 4 data logger provides easy monitoring and troubleshoot-
ing of pneumatic control systems. The unit is completely self-contained with a
1/4” quick-release pressure fitting to allow a fast and trouble-free connection. As
an added bonus, the SmartReader Plus 4 also monitors ambient temperature and
either external temperature (with thermistor probes) or temperature and relative
humidity together (with an RH/temperature probe). Probes and sensors are sold
separately through ACR.
