Note: I could not verify a current official Dwyer specification page specifically for catalog number MS-712. Dwyer’s current differential-pressure products confirm that this type of device is used for HVAC airflow, filter, and ventilation monitoring, but I would avoid adding an exact pressure range, contact rating, or dimensions to your listing unless those values are visible on the MS-712 label or datasheet.

Dimensions:

• Compact HVAC differential pressure switch construction
• Exact MS-712 dimensions should be confirmed from the product label/datasheet before listing

Weight:

• Exact weight not verified for MS-712
