It has keypad to programming the instrument. It has Stainless steel
Face plate, which is designed for wall mount Clean Room indication
where you need easy mounting mechanism. This instrument enables
you to measure differential pressure (DP) in the following fields:
The UNITECH “Differential Pressure Indicator : UT-1401” is specially
designed to indicate the Room pressure between two different areas.
The large 4½ digit, 0.4” high LED display is easy to read, even from a
distance. Two alarms can be selected for above or below set point
control, which can help the user to monitor the DP and to take
necessary actions to maintain the room conditions as per the
requirement or application.
