4-20mA 0 ~ 14pH IP66 Online pH Meter for Process Monitoring
APX1 - C1 is a measure of water pH and ORP value of real-time online monitoring controller, can access a variety of traditional pH or ORP compound sensor.
Advantages of pH/ORP controllers:
APX1 series pH/ORP controllers are small, compact and lightweight. They conform to the panel mounting of the cabinet.
The IP protection level of the shell is high, which can effectively protect the corrosive dust intrusion and rain spray of the external environment.
The instrument has a large display screen to display electrode measurements and other necessary management data.
The instrument's interface language can be customized for the user to calibrate the device and set various parameters by operating the controller panel keys.
The instrument connects and controls other equipment through relays. It can also use 4~20mA current signal or RS485 digital signal to transmit the instrument information.

pH ORP controller wiring demonstration:
Place the controller with the screen facing down on the foam pad.Use a phillips screwdriver to unscrew the screws of the back cover.Take out the cable glands.Insert the cable glands into the reserved hole,tighten the nut inside the rear cover.Loosen the nut on the outside of the rear cover.Insert the power cable into the gland on one side.Pass the pH sensor wire through the other side.Note: Do not cross the power line and the sensor line to prevent the drift of the measurement data caused by interference.The power cable has two ends.The brown live wire is connected to the terminal hole marked "L".The blue neutral wire is connected to the terminal hole marked "N".
pH ORP Controller Applications:
Water treatment monitoring: drinking water, surface water source
water quality, groundwater, environmental sewage discharge
monitoring, urban drainage network monitoring
Industrial process monitoring: chemical industry, petroleum, paper
making, food and medicine, PCB electroplating, etc
