The CS425 was manufactured by Druck for use in surface, groundwater, or hostile fluid applications.It was similar to the CS420 (also retired), but was not as accurate. The sensor's accuracy was ±0.25% FS, BSL (combined non-linearity, hysteresis, and repeatability). The CS425 featured a titanium body with an isolated diaphragm and NEMA6 (IP68) ingress protection to 2300 feet of water.
