Water Analysis PH ORP Tester RS485 Self Diagnostic Technology

Product Specification

Water Analysis PH ORP Tester RS485 With Self - Diagnostic Technology

There are many kinds of variable valence ions and dissolved oxygen in natural water bodies. When some sewage is discharged into water, the water contains a lot of ions and organic substances. Due to the different nature of ions, oxidation-reduction reactions occur in the water body and tend to balance. Therefore, it is not a single redox system in natural water bodies, but a mixed redox system. The DRFN pH/ORP tester uses a galvanic cell electrode (pH sensor) with a salt bridge to detect the change in the concentration of hydrogen ions in the solution. This change affects the electrode potential. The electrode is usually made of glass, commonly known as PH glass electrode measurement method.

Introduction Of The PH ORP Tester

• The APX1-G2A/G2D has a 128*64 large screen graphic dot matrix LCD screen, multi-language display options, rich content;

• The housing protection grade is IP66, it can effectively isolate the pollution of the external environment;
• There are 2 SPST multifunction relays that can be set;
• Two high-precision 0/4~20mA current output;
• There is a two-wire RS485 interface, the communication protocol is standard MODBUS RTU, and it also supports JavaScript Object Notation text data format;
• The menu password can be set to facilitate hierarchical management;
• Shortcut keys help you perform daily essential maintenance without entering the menu.

Parameters 

Advantages Of The PH ORP Tester

1. There are two settable 0/4-20mA active current loop output, each current output allows the user to specify the measured value: pH, ORP, or temperature. At the same time, the user can define the output range corresponding to the maximum and minimum current value of each output, whether it is forward or reverse. For long-distance output, current calibration can be used to ensure the accuracy of the output. The current resolution is 0.00025 (16-bit AD), and the maximum load is 1000Ω.

2. All the configuration entered by the user is kept indefinitely, even if there is no power, the data will not be lost. The output and control configuration of the pH/ORP meter is additionally recorded in a configuration list, which is convenient for users to record and verify.

Applications Of The PH ORP Tester

Water treatment monitoring: Drinking water, surface water, water quality, groundwater, swimming pool, etc.

Industrial process monitoring and dosing control management: Chemical, petroleum, paper, food and medicine, electroplating, PCB manufacturing, etc.
