How to Use the MW801 PRO

1. Calibrate with standard buffer solutions: Before using the MW801 for testing, it’s important to calibrate the meter using standard buffer solutions that are specifically designed for pH and EC calibration. Calibration ensures the accuracy of your readings by aligning the meter’s measurements with known reference values. Always calibrate your meter at least once a month or more frequently, depending on usage, to ensure precise results.
2. Submerge the probe in the water or nutrient solution: Place the probe of the MW801 directly into the water or nutrient solution you are testing. Ensure that the probe is fully immersed in the liquid to get an accurate reading. This will allow the sensors in the probe to measure the pH, EC, and TDS levels of the solution effectively.
3. Gently stir for an accurate reading: To ensure the most accurate and consistent results, gently stir the probe in the water or nutrient solution. Stirring helps distribute the solution evenly around the probe, preventing localized imbalances in the solution that could lead to inaccurate readings. It also helps eliminate air bubbles that may form around the probe, which can interfere with the measurement process.
4. Adjust pH and nutrient levels as needed: After taking the reading, compare the results with the desired values for your specific plants or system. If the readings are out of range, use the appropriate pH adjustment solutions or nutrient additives to bring the levels into the optimal range. Regular monitoring and adjusting of pH and nutrient levels is crucial to maintaining a healthy growing environment for plants.
5. Clean and store the probe properly for longevity: After each use, clean the probe to ensure that it remains free of any residue or contaminants that could affect future measurements. Always store the probe in a buffer or storage solution to keep it in good condition and prevent it from drying out or becoming damaged. This helps maintain the longevity and accuracy of the probe over time.

Proper Meter Care & Maintenance

Essential Tips for Long-Lasting Performance:

• Store the probe properly in buffer or storage solution (not water): After use, always store the probe in a proper storage solution, not in water. Storage solutions are specifically designed to keep the probe’s sensors moist and functional, whereas water can cause the probe to dry out or corrode over time, compromising its effectiveness. Using a storage solution preserves the accuracy of your readings and ensures the probe is always ready for use.
• Clean regularly by soaking in pH and EC cleaning solution: Regular cleaning is vital for maintaining the performance of your MW801. Soak the probe in a pH and EC cleaning solution to remove any buildup of dirt, oils, or salts that could interfere with the meter’s readings. Over time, residue can accumulate on the probe’s sensors, leading to inaccurate results. Cleaning the probe after each use (or at least weekly, depending on usage) helps maintain its sensitivity and reliability.
• Calibrate after cleaning and before testing to maintain accuracy: Cleaning can slightly alter the probe’s performance, so it's important to recalibrate the meter after cleaning. Calibration ensures that the meter is still giving you accurate readings, especially if there are any slight changes in sensor response due to cleaning. Always calibrate the meter before taking measurements to ensure that the results are reliable.
• Gently stir the probe in the sample for the most reliable results: As mentioned in the usage instructions, gently stirring the probe in the solution ensures that the reading is consistent and accurate. It also helps avoid air bubbles or local temperature variations that can lead to discrepancies in the readings. This simple step ensures that your results are as precise as possible, whether you’re measuring pH, EC, or TDS.
