SmartReader7 (SR-007)

The SmartReader7 is a versatile data logger that can monitor and record a varity of different process signals including the popular 4-20mA and 0.5V. With is seven input channels, the logger is ideal for monitoring (through commercially available transducers) a wide varity of measurement parameters such as flow, level, pressure, an much more. All process signals can be displayed in their own engineering units using the simple equation in ACR´s TrendReader Standard Software.
