The Model PKII is a self-regulating, portable, primary type pressure standard designed for use in ranges
The Model PKII is a self-regulating, portable, primary type pressure standard designed for use in ranges from 4" H2O through 30 psi. The PKH is self-contained in a rugged plastic case designed for “closed-case” operation, eliminating wind problems. The weights are stacked in foam pockets in the case for convenient handling. Additional space is provided in the case and cover for accessory equipment and tools.
