Eight-Channel Process Signal Data Logger
Model SmartReader Plus 7


The SmartReader Plus 7 data logger is a versatile data logger for easy recording of common process signal variables. With seven input channels, the logger is ideal for monitoring (through commercially available transducers) a wide variety of measurement parameters.)

Applications
Monitoring wind speed, flow, tank level, pressure, current, voltage, power, SCADA troubleshooting, etc.
