4-20mA Relays Dosing Control 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.

The pH/ORP controller supports a variety of installation methods and comes with the necessary installation accessories. The pH/ORP controller (APX1-C1) can be installed in a cabinet or on a wall mount. The built-in support frame can be used to install a controller in either of the two ways. In the first cabinet installation method, place the table in the cabinet, open it, and secure it behind the cabinet using a support frame. The second kind of wall hanging installation, according to the gap distance of the wall hanging metal bracket holes, punch two screws in the wall, put the table in the metal bracket and fixed with the support frame, the installation is completed.
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
