PH-018(485) RS485 Industrial on-line PH Controller
 
• The intelligent: using micro processing chip, complete pH measurement, temperature measurement, temperature compensation, automatic communication network, man-machine interface and other functions.
• Anti - interference: mA output, RS485 communication and measurement circuit adopts photoelectric isolation technology, has good electromagnetic compatibility, strong anti-interference ability.
• The multi parameter display: time, temperature, pH, mA output, high and low limit setting value and the alarm output and displayed on the LCD screen.
• The display: 320*240 color LCD screen, high resolution, beautiful appearance, WIN8 METRO style menu, friendly man-machine interface.
• The RS485 communication: follow MODBUS RTU standard communication protocol, multi unit network monitoring and automatic control of computer connection.
• The industrial control watchdog: ensure that the instrument do not crash.
• The time display: built-in clock chip, display the current date and time.
• The temperature compensation, automatic temperature compensation, you can also manually input the temperature, manual temperature compensation.
• It is widely used in monitoring and control of pH in thermal power, chemical fertilizer, metallurgy, environmental protection, pharmaceutical, biochemical, aquaculture, greenhouse cultivation, food and tap water and other industries.
