Profile
MW-ORP101 sensor is a primary battery type ORP water quality detection sensor. Using the relationship between the ORP value of the test solution and the measured potential difference, the ORP value of the solution to be tested is determined by the potential difference measured by the working battery composed of the electrode and the counter electrode in the solution to be measured through the sensor.
Sensor characteristics
High precision, fast response, good stability, small size, low power
consumption, easy to carry.

Instructions
- Remove electrode protective cover from sensor port and soak it in 3M KCL resolution for 8 hours.
- After soaking, rinse the sensor electrode end with a small amount of pure water or de-ionized water.
- Connect the sensor port to the ORP test instrument and place it in the solution to be tested for testing after being stabilized for 3 minutes.
- After the test is completed, rinse the sensor electrode end with a small amount of pure water or deionized water.
- Dry the cleaned sensor, put a protective cover on the electrode end, and store it at room temperature.

Precautions
- The protective cover must be removed before using the sensor
- If there is white crystal on the sensor electrode end, rinse it with de- ionized water.
- When the sensor is initial use or used again after a long term storage, the electrode port should be immersed in 3M KCL resolution for 2 hours for activation.
- If there are contaminants on the sensor electrode end, it can be treated with corresponding reagents, see Table 3 for details.
