Analog PH Sensor Suitable For Chemical Wastewater

The Daruifuno ASR300 ORP Sensor is a cutting-edge, high-performance instrument specifically engineered for accurate and reliable measurement of Oxidation-Reduction Potential (ORP) across diverse industrial and environmental applications. This sensor is housed in a durable ABS plastic body, making it an ideal and robust choice for critical tasks in wastewater treatment, industrial production, and comprehensive environmental monitoring. It excels in managing water quality across various challenging areas, including domestic sewage, agricultural runoff, industrial wastewater streams, and sensitive aquaculture systems.

Robust Design for Long-Term Stability

The ASR300 is meticulously designed for long-term stability even in complex and chemically demanding media. At the core of its precision is a highly responsive platinum flat measuring electrode, which facilitates a wide and precise measurement range of ± 1500mV.

The sensor incorporates a robust reference system to ensure consistent performance. It features an Ag/AgCl reference electrode meticulously protected by a double salt bridge and a KCl gel reference system. This advanced design is critical for minimizing electrolyte depletion and significantly resisting fouling, guaranteeing consistent and accurate performance even in dirty or chemically challenging solutions.

High-Quality Electrical SpecificationsThe key electrical specifications of the ASR300 confirm its high quality and operational accuracy, guaranteeing responsive and precise redox measurements. The specified Zero Position (E_0) is ±20 mV at 25℃, and the Slope percentage is robustly greater than 95% at $25℃. These parameters validate the sensor's ability to deliver high-precision redox potential data consistently.

Daruifuno ASR300: Optimized Operating Parameters and Automated Cleaning CapabilitiesThe Daruifuno ASR300 ORP Sensor is engineered for dependable operation across standard and challenging water process conditions. Its operating parameters are carefully defined to ensure optimal performance and longevity in industrial settings.

Robust Operating Environment
The ASR300 is built to handle temperatures ranging from 0℃ to 60℃ at 4Bar, and can sustain temperatures up to 80℃ at 2Bar. To achieve optimal performance and reading stability, the recommended sample flow rate should be carefully maintained between 0.001m/s and 0.5 m/s. The sensor also supports flexibility in integration through customization for various temperature compensation units, including industry standards such as PT1000, PT100, and NTC10K.

Advanced Automated Cleaning Feature
A critical feature designed for high-maintenance and demanding applications is the ASR300's compatibility with an optional cleaning connector. This capability is vital for ensuring long-term accuracy and minimizing manual intervention.When the ASR300 is connected to a compatible Daruifuno PH/ORP controller, the user gains the ability to configure a fully automated self-cleaning cycle. This functionality allows for the precise control of the cleaning time interval and the cleaning frequency. This feature is absolutely essential for actively preventing electrode coating, which is the primary cause of measurement drift, thereby significantly reducing the need for costly and time-consuming manual maintenance in challenging environments.

• Compact all-in-one design
