The OMEGA™ HHP350 Series smart manometer brings high precision and value to handheld manometer users. Standard accuracy is ±0.05% FS including temperature effects with ±0.025% FS optional. Models are available for gage absolute or differential pressure with available ranges from 58 mbar (28 inH2O) to 138 bar (2000 psi).
Additional features for the HHP350 Series include MIN/MAX capture adjustable damping rates and user selectable auto shut-off time period. It can also document up to 240 readings automatically or manually. Saved readings can be recalled at any time.

The HHP351 series is being permanently replaced by our HHP400 series. The HHP400 equivalent is for the old HHP351/2 or 360 model that you may have previously purchased
