netvox R900PD01O1 Wireless Residual Chlorine Sensor

Selelekela

R900PD01O1 is a wireless water pH, turbidity, and residual chlorine sensor with a digital output. It transmits digital signals to a third-party device when a value exceeds the threshold. With up to 7 flexible installation options, R900PD01O1 integrates easily into various environments. In addition, with support for Netvox NFC app, users can easily configure settings, update firmware, and access data simply by tapping their smartphone to the device.

LoRa Wireless Technology
LoRa is a wireless communication technology famous for its long-distance transmission and low power consumption. Compared with other communication methods, LoRa spread spectrum modulation technique greatly extends the communication distance. It can be widely used in any case that requires long-distance and low-data wireless communications. For example, ho bala mithara ka mokhoa o itekanetseng, lisebelisoa tsa ho iketsetsa moaho, lisebelisoa tsa ts'ireletso tse se nang mohala, le tlhahlobo ea indasteri. E na le likarolo tse kang boholo bo nyane, tšebeliso e tlase ea matla, sebaka se selelele sa phetisetso, bokhoni bo matla ba ho thibela tšitiso, joalo-joalo.

Tlhokomelo

• Before using the pH sensor, please clean it with distilled water (or deionized water), and dry it with filter paper to prevent impurities from entering the liquid to be tested. After cleaning, dip 1/3 of the sensor into a liquid.
• Please clean the sensor when it’s not in use. Insert it in a protective case or a container with 3.5 mol/L potassium chloride solution.
• Please check if the terminal is dry. If it is stained, wipe it with absolute alcohol and dry it. Avoid long-term immersion in distilled water or protein solution and prevent contact with silicone oil.
• For an aging sensor, its glass membrane may become translucent or have sediments, which can be washed with dilute hydrochloric acid and rinsed with water.

When the calibration and measurement cannot be performed after the sensor is maintained based on the instructions, please replace the electrode.

Sensor ea Turbidity

1. Ka kopo, tlosa sekoaelo sa polasetiki hloohong ea sensor ea turbidity.
2. Kenya sensor ea turbidity 5cm hole le lebota le 10cm ho tloha tlase.

Tlhokomelo

• Sebaka sa Kantle sa Sensor:
  Use tap water to clean the external surface of the sensor. If there are still debris remaining, wipe it with a soft moistened cloth. For some stubborn dirt, users can add some household detergent to the tap water to clean it.
• Sheba Cable ea Sensor:
  The cable should not be taut during normal operation; otherwise, the internal wires of the cable may break, and the sensor cannot work normally.
• Sheba hore na karolo ea ho lekanya ea sensor e silafetse le hore na brush ea ho hloekisa e tloaelehile.

The sensor generally does not require daily maintenance. In there is a noticeable malfunction, do not attempt to disassemble or repair it yourself. Please contact us as soon as possible.

Tlhokomelo

• After using the sensor, please rinse the head thoroughly with clean water and cover it with the protective cap.
• If dirt or mineral deposits accumulate on the electrode membrane, it may reduce sensitivity and affect measurement results. Please ensure the platinum ring area remains clean.
• If the platinum ring appears rough or covered with contaminants after measurement, please clean it using the following methods (for reference):
  • Inorganic contamination: Soak the electrode in 0.1 mol/L dilute hydrochloric acid for 15 minutes. Gently wipe the platinum ring with a cotton swab, then rinse with tap water.
  • Organic or oil-based contamination: Soak the electrode in tap water containing a small amount of detergent (e.g., dishwashing liquid). Thoroughly clean the sensor’s sensing surface. Gently wipe the platinum ring with a cotton swab, then rinse with tap water.
• If an oxide film has formed on the platinum ring, polish the sensing surface gently using toothpaste or 1000-grit fine sandpaper, then rinse with tap water. The platinum ring is connected to glass, so please handle it carefully during polishing.
• The electrode typically has a service life of about one year. Please replace it if it’s ageing.
