Why need Sodium hypochlorite (NaClO) pressure measurement?

Sodium hypochlorite (NaClO) is an inorganic substance .It is a kind of hypochlorite and is the most common "chlorine" bleach in household washing. It has a chlorine-like smell. Dissolved in water, it is a slightly yellow aqueous solution. Chlorine is dissolved in cold and dilute sodium hydroxide solution to produce sodium hypochlorite, sodium chloride and water. Sodium hypochlorite (NaClO) is mainly used in bleaching, industrial wastewater treatment, papermaking, textiles, pharmaceuticals, fine chemicals, sanitation and disinfection, etc.

Sodium hypochlorite (NaClO) is a kind of aggressive fluids; it is not easy to measure pressure for its corrosivity. Also Sodium hypochlorite (NaClO) could have very low pressure rating, such as -1000 ~1000 mmWC, or even lower than 60Kpa or negative pressure. Glycerine filled case manometer is often requested.

Sodium hypochlorite (NaClO) pressure gauge

• Manometer dial:  6” or 4” , bottom entry ,local mounting
• Glycerin-filled dial option
• Movement 304, socket and bourdon tube 316 stainless steel
• Diaphragm SS316+PTFE
• Process: 1"ANSI B16.5 150#RF Flanged 316SS+PTFE lining (or option with 2”, 3” flanges)
• All wet parts is Teflon for corrosive NaClO measurement
• Pressure units: mmWC , Kpa
