Description
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.
