FAQ

1. Periodic Calibration: Calibrate the equipment before use and after long periods of non-use to ensure accurate measurement.

2. Clean After Each Use: Flush electrodes with clean water after each use to maintain performance and extend equipment life.

3. Avoid Extreme Conditions: Do not measure highly corrosive liquids or immerse the device in liquids for long periods of time.

4.Timely Battery Replacement: If the screen is dimmed or the device cannot be turned on, replace the three LR44 1.5V batteries.

5. Proper Storage: Store in a dry and cool place, avoid direct sunlight, prevent damage and prolong product life.

The warranty period of the main device is 1 year for non-human reasons, the electrodes is consumables, the warranty period is 3 months, most of our products are designed with replaceable electrodes, need to be equipped with electrodes can contact us.

Yes, it's all calibrated before it leave the factory. You can use it as soon as you get it.

If the pH value keeps showing 6.86, it may be a fault of the meter, you can restart the instrument and recalibrate it. If it still does not work, please check whether the electrode is damaged and replace the electrode.

We have a variety of functional parameters, such as pH, TDS, EC,ORP, DO dissolved oxygen meter, salt, residual chlorine, turbidity, hardness, ammonia nitrogen, nitrite, etc. Please see the functional parameters clearly when purchase, if you do not know how to choose it can contact us.

Can not. Because the medium of water and soil is different and the conductivity is different, the data error will be particularly large. It is recommended to choose professional testing equipment.

Yes, The correct calibration is also with distilled or purified water.

The pH meter works by measuring the potential difference between the glass electrode and the reference electrode. When the glass electrode is immersed in the solution, it generates a voltage based on the hydrogen ion concentration in the solution. This potential difference is then converted into a pH value by the instrument, indicating the acidity or alkalinity of the solution.

Factory Reset Steps:

1. Turn off the pH meter.2.Press and hold the reset button: Some models may require pressing and holding both the "CAL" and "ON/OFF" buttons simultaneously to initiate the reset.

2. Wait for confirmation: After holding the buttons, the display should show a message such as "Reset", "Factory Settings Restored", or "Recalibration Complete". This will restore all settings, including calibration and stored data.

pH Meters use in  Common area:

1. Water Quality Testing: such as swimming pools, drinking water, and aquariums.

2. Pharmaceutical Industry: pH meters help pharmaceutical manufacturers ensure that solutions, such as medications, saline solutions, and other liquid products, maintain the proper pH levels for efficacy and safety.

3. Agriculture and Soil Testing: pH meters are used in agriculture to test soil pH. Different plants thrive in different pH range

4. Food and Beverage Industry:In food processing, pH meters are used to monitor the acidity of products like sauces, cheese, fruit juices, and vinegar to ensure product consistency and safety.

5. Aquaculture:In fish farming, pH meters are crucial for maintaining optimal water conditions. Fish and other aquatic organisms require specific pH ranges to thrive.

6. Laboratory and Scientific Research:pH meters are essential in research labs to measure the pH of solutions, whether in chemical reactions, biological studies, or environmental monitoring.

7. Environmental Monitoring:pH meters are used to assess the pH of natural waters (such as rivers, lakes, and oceans) to monitor the health of ecosystems.

8. Cosmetics and Personal Care Products:In the cosmetics industry, pH meters are used to ensure that products like lotions, shampoos, and soaps have a skin-friendly pH balance.

9. Industrial Applications:pH meters are used in various industries such as chemicals, pharmaceuticals, and food production to monitor and control the pH of solutions or reactions.

10. In brewing or winemaking, pH meters are crucial to monitor fermentation processes.

Dipping the pH meter in KCl solution helps to:

1. Stabilize the reference electrode potential.

2. Ensure proper ion conductivity.

3. Prevent contamination and damage to the electrode.

4. Maintain the accuracy and reliability of pH measurements.

5. Therefore, the use of KCl solution is crucial for accurate, consistent, and long-lasting performance of a pH meter.

pH meter calibration is critical to ensure that you obtain accurate, consistent, and reliable pH measurements. It compensates for electrode drift, environmental factors, and other variables that can affect the performance of the pH meter. Regular calibration is essential for maintaining measurement accuracy, ensuring product quality, and complying with regulatory standards.

1. Frequency of calibration depends on how frequently the pH meter is used and the precision required in measurements. In general:For frequent use or in critical applications, calibration should be done daily or before each use.

2. For less frequent use, calibration may be needed every few weeks or before any major testing.

3. Always calibrate when using the meter after a long period of inactivity or after replacing the electrode.
