OTA RS485 PH ORP Analyzer 14pH Differential Signal With Temperature Compensation
Introduction Of The PH ORP Analyzer
- The PH ORP meter water quality transmitter with differential signal input is compatible with the DRFN pH sensor with grounded electrode;
- The housing protection grade is IP66, it can effectively isolate the pollution of the external environment;
- The PH ORP analyzer has a 3.2-inch display screen, using 128*64 black and white graphic dot matrix LCD;
-
There are two adjustable 0/4~20 mA active current loop outputs, each of which allows the user to specify the measurement value, pH, ORP, or corresponding temperature.
- This meter has time history and data recording functions, it can be accurate to the second and record measurement data on time;
- There are 2 SPST multifunction relays that can be set.
- There is a two-wire RS485 interface, the communication protocol is standard MODBUS RTU, and it also supports JavaScript Object Notation text data format.

Advantages Of The PH ORP Analyzer
1. The instrument is equipped with OTA(over-the-air)download technology. As an intelligent configuration option of the instrument, it can remotely upgrade software, diagnose faults, and assist in setting instrument parameters. This approach not only reduces the workload of on-site service but also minimizes the waiting time for service.
2. As the temperature of the aqueous solution changes, the concentration of hydrogen ions and hydroxide ions ionized from the aqueous solution will also change. The pH ORP analyzer has a temperature automatic compensation function, and when the temperature of the instrument changes, it will also compensate the hardware changes caused by temperature drift.
Applications Of The PH ORP Analyzer
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.
