Process Signal Measurement Solution
Eight Channel Process Signal Data Logger
Recording process signals is easy and convenient with the SmartReader Plus 7. With seven input channels it is ideal for monitoring (through commercially available transducers) a wide variety of measurement parameters. All process signals can be displayed in their own engineering units using the simple equation editor in ACR’s TrendReader® Software for Windows®.
