Pressure Gauge

Harvard pressure gauges for swimming pools and spas are durable, corrosion-resistant instruments designed for monitoring filter pressure, typically featuring a 2-inch or 2.5-inch dial, brass or stainless steel components, and a 1/4-inch bottom or back mount. Ranging from 0-30 to 0-100 PSI, they are available in liquid-filled or dry polypropylene cases
