| | | This unit features pressure, vacuum, or differential measurement for use with clean dry, gases. The unit is powered by a 9-volt battery. Available Units: Inches of water, PSIG, PSIA, mbar, bar, mm Hg A, & inches Hg A Accuracy: ±0.25% of reading ± 5 digits @ 22°C (includes the combined effects of linearity, repeatability and hysteresis) 350 Series Smart Manometer The 350 Series Smart Manometers are micro-processor-based pressure sensing devices that can measure gauge, differential, absolute or vacuum pressure with an accuracy of ±0.025% of FS. The display can read out in any of eleven engineering units and can also be scaled to special user units for pressure. A MIN/MAX key captures the extremes of pulsating pressure signals and a HOLD key freezes the display at any point of interest. | | |

This combination of accuracy and fluid compatibility makes the 355 ideal for test or process applications. The model 355 has a programmable altitude function that allows the user to enter the site altitude above sea level in feet or meters. This allows the user to chose between displaying local barometric pressure or pressure corrected to sea level. The altitude function used with the Min/Max and Tare makes the model 355 useful as a surveyor's tool by accurately measuring changes in altitude. | | |
