Product Description

The ABB IM/C1900-OGR is a specialized model within the C1900 Series Circular Chart Recorders, designed as an Operating Guide Recorder (OGR). It continuously records one or two process variables—such as temperature, pressure, or flow rate—onto a 10-inch circular chart, delivering a clear, analog display of process performance over time.

What sets the OGR apart is its enhanced operator guidance capabilities, including preset alarm thresholds and printed operator instructions directly on the chart. These features make it especially valuable for critical or regulated applications where compliance and clarity are essential.
