The intelligent pH/ORP controller and temperature detector PC-3218 controller arePH/ORP/temperature three in onecontroller.PC-3218 type,It is an industrial pH、ORP， temperatureOnline analyzer is a brand new pH analyzer/ORP/TemperatureThe analyzer has a high degree of intelligence and flexibility, and can simultaneously measure pH/ORPAnd temperature, widely used in urban sewage treatment plants, electricity, water supply, medicine, chemical, food and other industries, to regulate the pH of solutions/ORPContinuous measurement of values

basic function

1.The factory standard interface in both Chinese and English allows for easy switching and simple operation.

2.Automatic and manual temperature compensation can be selected to meet various user needs.

3.Two 4-20mA outputs, corresponding to PH &ORPValue, using isolation technology, strong anti-interference ability.

4.The high and low points of the two relays can be switched freely, and the hysteresis can be adjusted freely.

5. 480*800 IPSLCD, clear display,10-100%Brightness can be freely set.

6.Protection level IP65, suitable for outdoor use.

7.Password management function to prevent misoperation by non professionals.
