Service intended
P256 series are made with a solid plate wall and a blow-out back. Its stainless steel case and cover have a good appearance. It has the excellent proof against corrosion and chemical attack. Suitable for protection against damage to the measuring element when high overpressure is applied to the gauge instantaneously. Max overpressure is up to 4 times of measuring range.
