ORP Analyzer



ORP Analyzer


SMART series intelligent multi-parameter universal controller has high accuracy, its unique professional design can be applied in water, chemical, pharmaceutical, food and hygiene in the production process of the most extreme physical and chemical environments. SMART series intelligent multi-parameter universal controller has modular bus structure, highly scalable functionality, high reliability and comfortable operation.


ORP is a measure of the oxidation or reducibility of the process medium. For different aqueous solutes, the measurement range is between -1500mv and 1500mv. The measuring electrode usually uses precious metals (platinum or gold).

Typical application

▲Source water monitoring

▲Filter monitoring

▲Drinking water quality monitoring

▲Separation process monitoring

▲Cooling water monitoring

▲Circulating water detection

▲Sludge treatment monitoring

▲Aeration tank monitoring


★Smart digital MEMS sensor

★Sensor self-diagnosis, proactively reminding maintenance and management

★Automatically completes all compensation and measurement algorithms

★Quick response sensor

IP68 Sensor

★Electrochemical sensor

★KCl plastic gel electrolyte

★PTFE porous permeable material is durable

★Good robustness

★Good stain resistance

★The same electrode can measure PH/ORP at the same time

★Fully automatic cleaning

★The MEMS sensor eliminates the following problems: corrosion, contact problems, salt bridges, moisture, leakage, high resistance connections, and grounding.


Please note that the installation is more than 15 degrees above the horizontal plane, the first installation and use will take about 20 minutes of polarization time. When not in use for a long time, the PH or ORP electrode can be kept moist (the best storage solution is potassium chloride solution with pH 7 or 3mol, and it must be noted that it cannot be stored in deionized water and acid-base solutions). White potassium chloride crystals appear, which will not affect the measurement after cleaning the surface. If the sensor becomes dry during storage, you can soak the sensor in a pH 7 or 3 mol potassium chloride solution for a period of time, and the sensor will restore the water-containing glass membrane and the reference diaphragm.

Application case

Sewage: water inlet, activated sludge and water outlet pipe.
