Barton chart recorders are the industry standard for accurate, reliable measurement and recording of pressure, differential pressure, andtemperature in a wide variety of applications. In addition, DP models utilize Barton’s rupture-proof bellows DPU as
the actuating unit – with features like overrange protection and pulsation dampening (on somemodels).

Common Components
• Case – is made of rugged, lightweight die-cast aluminum that features a built-in rain-shield.
