Fluke 922 Electronic Manometer
In stock (can be backordered)
This is my favourite Digital Manometer for pairing with a Pitot tube for Duct traverse measurements (in Pascals or direct in m/s).
A bit more expensive than the TSI Airflow equivalent but I particularly like the rubber casing which will give it a fair degree of protection (and protection for your investment!) in the event of being dropped.
It’s made by Fluke so the standard of build and accuracy are both excellent. Comes complete with a soft carry pouch, manual and batteries.
