Model HHP91 is a precision manometer for automotive, HVAC, laboratories, and general industrial applications. The unit comes complete with a built-in sensor with dual inputs for gage or differential measurements. It is compatible with air or non-corrosive and non-ionized gases and liquids. Either port measures the full range. P1 is positive with increasing pressure, P2 is negative with increasing pressure. Eight selectable pressure ranges make this instrument compatible with all measuring systems. The readings are easy to read, displayed in large 15 mm (0.6") high digits.

Hi would this or another unit come with an nist certificate.
Asked by: Gilly8830
Thank you for your inquiry.
This unit doesn't come with a N.I.S.T. cert.
Please contact the pressure group to discuss options.
There are a few and would need to discuss your application in detail.

I am looking for a differential pressure meter that comes with software, so I can store the data on a computer and view it in real-time.
We need the meter for scientific purposes.
Price doesn't matter.
Can you help me?
