The HHC280 Series of handheld manometers are offered in two different models: absolute pressure manometer and precision differential manometer. Both models present auto power-off and backlight with auto-off features.

Differential Manometer - HHC280

Eight Selectable Units: mmH2O, mmHg, psi, inH2O, inHg, hPa, mbar, Pa, plus m/s and fmp (for air velocity)
Range: 0 to 100 hPa/0 to 1019.7 mmH2O
Resolution: 0.1 hPa/0.1 mmH2O
±0.03 hPa (0 to 0.30 hPa)
±0.05 hPa (0.31 to 1.00 hPa)
±0.1 hPa + 1.5% or rdg (rest of range)
±0.3 mmH2O (0 to 3.0 mmH2O)
±0.5 mmH2O (3.1 to 10.2 mmH2O)
±1.02 mmH2O + 1.5% of rdg (rest of range)
Operating Temperature: 0 to 50°C (32 to 122°F)
Power: 2 “AAA” batteries (included)
Battery Life: 85 hours typical with alkaline batteries
Dimensions: 24.7 x 50.9 x 132.9 mm (0.98 x 2.0 x 5.2")
Weight: 113 g (4.0 oz)

Absolute Pressure Meter - HHC281

Eight Selectable Units: hPa, mbar, Pa, mmH2O, mmHg, inH2O, inHg, psi, plus m and ft (for altitude)
Range: 300 to 1200 hPa
Resolution: 0.1 hPa
Accuracy: ±3 hPa
Operating Temperature: 0 to 50°C (32 to 122°F)
Power: 2 “AAA” batteries (included)
Battery Life: 600 hours typical with alkaline batteries
Dimensions: 24.7 x 50.9 x 132.9 mm (0.98 x 2.0 x 5.2")
Weight: 120 g (4.2 oz)
Comes complete with batteries, carrying strap, and protection cap.

Rated 3 out of 5 by from Good Basic Instrument I purchased this Manometer for laboratory testing on residential HVAC duct systems. I am measuring duct pressure "Inches/WC. The specifications stated the Instrument had an "averaging" feature which I badly needed. Turns out the "averaging" feature was only for wind speed, so that was very disappointing. But the instrument works very well and provides stable readings.

Rated 5 out of 5 by from Well-priced, accurate, and arrived quickly! It is almost impossible to find an absolute pressure gauge that can cover these ranges. It was relatively inexpensive, accurate, and I received it in just a couple of days after a very easy ordering process. Great product!

Would this unit be suitable for measuring pressure differentials across adjacent cleanrooms of a cleanroom suite? In particular, I want to use the absolute pressure unit because I don't want to drill holes in the walls separating the adjacent walls.

Yes. You can move the meter from room to room and monitor the change in the readings.

What is the resolution of HHC280 when measuring under 100 Pa? The datasheet is a bit confusing. Is it 10 Pa or 1Pa?

Asked by: RJag
Thank you for your inquiry, the Resolution is : 0.1 hpa/0.1 mmH2O

What we can do in case of OOT ? Thanks in advance

Asked by: JW1964
If the HHC280 unit is out of tolerance it would need to be returned to us for evaluation. There are no field calibration procedures available.
