Applies a high accuracy MEMS sensor and digital technology.
This digital differential pressure gauge can measure positive, negative, or differential pressure.
It can completely replace the traditional pointer mechanical gauge.
The digital differential pressure gauge can measure the system pressure of fans, blowers, filters, furnace drafts, and orifice plates.
There are no movable parts with zero effect on vibration.
This digital differential pressure gauge has a very thin enclosure (the flush thickness is only 33mm) which makes it great for surface, panel or flush mounts.
The hole for the flush mount is at the industry standard of 114mm.
State of art housing design, with large LCD or LED display
