Applications：

Industrial on-line acid/alkali/salt concentration monitor

is a water quality on-line controller with microprocessor.

The instrument is widely used in thermal power,

chemical industry, steel pickling and other industries,

such as the regeneration of ion exchange resin in power

plant, chemical and chemical industrial process, etc.,

to continuously detect and control the concentration

of chemical acid or alkali in aqueous solution.

Feature：

●LCD display

●Intelligent menu operation

●Data Record & Curve Display

●Manual and automatic temp. compensation

●Three sets of relay control switches

●High alarm & low alarm, hysteresis control

●4-20mA&RS485 Multiple output modes

●Concentration,temperature & current valuesimultaneously displayed in one screen

●Password protection function to preventmisoperation by non-staff
