Description
Barton chart recorders are the industry standard for accurate and reliable measurements and records of pressure, differential pressure and temperature in a wide variety of applications. In addition, DP models use Barton's rupture-proof bellows DPU as the drive unit, with features such as over-range protection and pulsation damping (in some models).
Case - is made of heavy-duty, lightweight die-cast aluminum that features a built-in rain guard. It is finished in electrostatic polyurethane powder paint that has a high resistance to weathering, scratches and industrial fumes. The aircraft door hinge (made of 302 SST) provides excellent resistance to salt spray and H2S. A closed neoprene gasket, non-absorbent for fluids and resistant to oils and most solvents, provides the seal between the door and the box.
Optional versions "S" use a stainless steel case or a "marine liner" resistant to corrosion for saltwater environments.
Chart Drive: available in battery and spring versions with a wide variety of chart speeds. All chart units, with a simple positive graph lock cube, are interchangeable.
NuFlo ™ graphics are made of "wood-free" paper, a special product of high quality and low shrinkage that eliminates eccentric and elliptical errors. The graphics are shrink wrapped to help maintain the factory default size until the user opens it. Once a letter box is opened, it can be stored in the sealed plastic bag provided.
