Description
The PK2-404WC-SS-1B/C uses range code 404WC, calibrated in inches of water column, with stainless steel weights (SS). It carries the 1B option suffix and the /C data and accessory package. The Ametek M&G PK II is a pneumatic deadweight pressure standard that uses the floating ball principle. A ceramic ball floats in a precision nozzle under a known weight load, and the instrument regulates its own output pressure from a clean gas supply, so the operator does not need to balance a piston by hand. Weights hang from an overhung carrier under a closed cover. Calibration labs and gas utilities use it as a reference for low-pressure gauges, transmitters and secondary standards.
