Omega’s PX409 series electronic barometers are high-accuracy barometers available in three inHg ranges or three hPa (mbar) ranges: 16 to 32 inHg, 26 to 32 inHg, 0 to 32 inHg or 0 to 1100 hPa, 550 to 1100 hPa or 880 to 1100 hPa (absolute pressure) for laboratory or industrial test applications. Models with integral cables (PX409) are IP67 while connector styles (PX419 and PX429) are IP65 rated. They feature all stainless steel construction, which makes them ideal for harsh industrial environments. Their high operating temperature, broad compensated range, and excellent temperature compensation allow stable readings in applications with fluctuating temperatures commonly found where barometric pressure must be monitored. Models are available with millivolt, voltage or current outputs.

The PX409 Barometric series is also available with a USB output and related software. Please see the PX409-USB as possible alternatives or contact our Pressure Engineering department.
