Two wire explosion-proof pH meter

The two-wire explosion-proof pH meter is one of the intelligent online chemical analyzers developed by our company. It has strong environmental adaptability, simple operation, and excellent testing performance, making it highly cost-effective and capable of measuring the pH value of solutions. It can be widely used for continuous monitoring of pH values in solutions such as thermal power, chemical fertilizers, metallurgy, environmental protection, pharmaceuticals, biochemistry, food, and tap water. The transmitter adopts an explosion-proof cast aluminum shell with good sealing performance and a protection level of up to IP67, which is particularly suitable for industrial places with harsh on-site environments and unsuitable for prolonged personnel stay.

　　Two wire explosion-proof pH meterMeasurement range: 0-14PH, output isolated 4-20mA, RS485, 4-20mA+, RS485 standard DC signals, can be supplied to display, record, control, regulation and other instruments or PLC, DCS, FCS systems. Built in software temperature compensation -30 ℃ -130 ℃, full screen Chinese menu, equipped with infrared remote control. The flange comes standard with DN50PN1.6, protective tube material 316L, and PTFE lining.
