PD6600 Loop Leader Loop-Powered Process Meter

Brand: Precision Digital Corporation

The Loop Leader PD6600 is a general-purpose, loop-powered, 1/8 DIN process meter.

The four front panel buttons make setup and programming of the meter simple and intuitive.

A dual-line display featuring five digits on the top line and eight digits on the bottom line, preprogrammed engineering units, and optional bar graph display: PD6604 or feet and inches display: PD6603 provide a clear and attractive presentation of the process.

The units of measure can be changed as needed within a unit class: e.g. volume, temperature, pressure, without the need to re-scale the meter.
