LED display Round shape Economical Digital Differential Pressure Gauge

 Multi functions design :

Models: D2L        :power is batery,AA battery X4, recommend LR6alkaline

               D2PL    :16~28VDC/AC or 85~265VAC

 Display: LCD or LED

Applications and features

1.Apply high accuracy MEMS sensor and digital technologies, can measure positive, negative or differential pressure. It can completely replace the traditional pointer mechanical gauges

2.It can measure fan and blower pressures, filter resistance, air velocity, pressure drop across orifice plates, differential pressure of medical or pharmaceutical machine, etc.

3. No any movable parts, no any effect on vibration.

4.With ultra-thin design of 33mm, it could be flush, surface or wall mount.

5.The accuracy is up to ±1% FS, with large LCD or LED display.

6.Function keys: zero reset, units select, display update time, automatic sleep time, etc.
