1、 Product Overview and Features

SHN-628The series of acid, alkali, and salt concentration meters can continuously detect the content of acid, alkali, and salt in aqueous solutions during industrial processes online. Mainly used in industrial production processes such as boiler feedwater treatment, chemical solution preparation, and environmental protection. This series of concentration meters adopts imported circuit components and electrodes, integrating measurement, conversion, and indication, with a novel design and reliable operation.

Adopting international new technology, it solves technical problems such as electrode polarization, constant instability, and measurement drift under high conductivity conditions. It can work continuously for two years without maintenance without crystallization and precipitation.

◆ Implemented two-wire transmission, making it convenient to communicate withDDZ-The control system consists of III series instruments and computers.

Modular electronic unit, earthquake resistant and moisture-proof, reliable operation, no distributed capacitance and electromagnetic wave influence, strong anti-interference ability.

◆ Overload protection circuit, when the measured solution exceeds the standard and the transmitter output is overloaded, the maximum current does not exceed30mA.
