Yokogawa Digital Indicator UM33A-000-11/LP/DC
Features
• A 14-segment, active (PV display color changing function) color LCD display is employed.
Two five-digit, high-resolution displays are possible. Alphabet letters can be displayed in an easy-to-read manner. The guide display shows parameter names.
• Easy to operate
Navigation keys (SET/ENTER and Up/Down/Left/ Right arrow keys)are employed to facilitate making settings.
• 65 mm depth
The small depth enables the mounting in a thin and small instrumented panel.
