OMEGA’s PX409 series electronic barometers are high-accuracy barometers available in three ranges:
16 to 32 inHg, 26 to 32 inHg, or
0 to 32 inHg (absolute pressure)
for laboratory or industrial test
applications. Models with integral
cables (PX409) are IP67, whilst
connector styles (PX419, PX429 and PX459)
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
The PX409 Barometric Pressure series is also available in metric configurations, with ranges in mbar (hPa) and G 1/4 (1/4"BSPP) metric fitting.
Please see the PXM409 series for complete details, or contact our Sales department for more information.
