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.

I Bought this unit and had it shipped overnight delivery for a emergency project and the unit had no battery with it. Not sure if it was even calibrated!

Hi would this or another unit come with an nist certificate.
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.

Dear sir/madam, 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?
We suggest you look at our HHP8200 Series manometer. These units are available with RS232 output and software

Can distilled water or sterile water be used on this manometer.
We recommend using deionized (DI) water with manometer.

Can these units be calibrated?
You can perform a calibration verification on the HHP91, however there are no adjustments that can be made to the unit.
