Online PH ORP Transmitter

Modbus RTU IP66 Online PH ORP Transmitter For The Monitoring Of Water Quality

The pH ORP transmitter can provide temperature compensation function, supporting pH sensor with temperature to measure the temperature change of aqueous solution. 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 measured PH value is constantly changing. If you need to get a more accurate measurement value, you must increase the temperature detection of the aqueous solution, perform temperature compensation or 25°C conversions.

PH ORP Transmitter Parameters

Advantages Of The PH ORP Transmitter

1. 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. At the same time, each output can define the range of the output value corresponding to the maximum and minimum current values, whether forward or reverse, is OK. The output accuracy can be guaranteed by current calibration during long-distance output. Resolution of the current is 0.00025(16 bit AD) and the maximum load is 1000 Ω.

2. The pH ORP transmitter can transmit analog and digital signals, or connect and control other devices through relays.

Applications Of The PH ORP Transmitter

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.
