Customer Questions & Answers

  • Question: What is the Ohaus 30087993 Replaceable pH Electrode?

    Answer: The Ohaus 30087993 is a replaceable pH electrode designed specifically to work with the ST20 pen meter. It allows users to accurately measure the pH level of various liquids, making it essential for laboratories and educational institutions. The electrode features a durable design, ensuring reliable performance over time. In practical use, this electrode is ideal for testing pH in soil samples, water quality analysis, and chemical solutions, providing precise readings essential for various scientific applications.
  • Question: How do I know if the Ohaus 30087993 electrode is compatible with my meter?

    Answer: The Ohaus 30087993 electrode is explicitly designed for compatibility with the ST20 pen meter. To verify compatibility, check your meter’s model number and specifications. If it matches the ST20 series, you can confidently use this electrode. Ensuring compatibility is crucial as it affects the accuracy of your pH measurements, especially in sensitive applications like aquatics, agriculture, or laboratory processes where precise pH readings are critical.
  • Question: How often should I replace the pH electrode?

    Answer: The frequency of replacing a pH electrode, like the Ohaus 30087993, largely depends on your usage and maintenance. Generally, it’s recommended to replace it when you notice drifting readings, sluggish response times, or when cleaning doesn’t improve the measurements. Regular calibration and proper cleaning can extend the life of the electrode. In practical scenarios, if you use it frequently for varied samples, checking monthly can help determine if a replacement is needed.
  • Question: Can I use the Ohaus 30087993 electrode for testing pool water?

    Answer: Yes, the Ohaus 30087993 electrode can be effectively used for testing swimming pool water. Accurate pH readings are vital for maintaining safe water quality in pools. By using this electrode with the ST20 pen meter, you can routinely monitor and adjust pH levels, ensuring a healthy environment for swimmers. Regular testing helps in preventing corrosion and scaling, thus extending the life of pool equipment and maintaining clear water.
  • Question: What types of liquids can I test with the Ohaus 30087993 electrode?

    Answer: The Ohaus 30087993 electrode is versatile and can be used to test a wide range of liquids, including drinking water, soil samples, and various chemical solutions. Its design allows for accurate readings in both light solutions and more complex mixtures. In research and commercial settings, this electrode is invaluable for applications like water quality testing and food and beverage production, where pH levels significantly impact safety and quality.
  • Question: How should I store the Ohaus 30087993 pH electrode?

    Answer: Proper storage of the Ohaus 30087993 pH electrode is essential to maintain its performance. Ideally, store the electrode in a storage solution specifically intended for pH probes when not in use. Avoid letting the electrode dry out, as this can damage the glass bulb and affect accuracy. In practice, overnight storage in a calibration solution can help keep the electrode ready for precise measurements the next day, particularly in a laboratory or educational setting.
  • Question: Is the Ohaus 30087993 electrode sensitive to temperature changes?

    Answer: Yes, the Ohaus 30087993 electrode can be sensitive to temperature variations, which may affect pH measurements. Using a meter that compensates for temperature can help ensure accuracy in different environments. Temperature fluctuations can influence ion activity and lead to erroneous readings. In laboratory settings, always allow the sample to reach room temperature and use the ST20 meter's temperature compensation feature for the best results.
  • Question: What is the lifespan of the Ohaus 30087993 pH electrode?

    Answer: The lifespan of the Ohaus 30087993 pH electrode can vary based on usage and maintenance but typically lasts several months to a few years. Regular calibration and proper cleaning can significantly prolong its lifespan. Noticing early signs of wear, such as erratic readings or degraded tips, can help you decide when to replace the electrode. In practical terms, routine checks after heavy use can prevent unexpected failures during critical testing periods.
  • Question: Can I use this electrode with other brands of pH meters?

    Answer: The Ohaus 30087993 electrode is specifically designed for the ST20 pen meter. While it may fit other pH meters, compatibility is not guaranteed, and performance can be compromised. Using a dedicated electrode for each specific meter ensures optimal accuracy and functionality. In scenarios where multiple meters are in use, always refer to manufacturer guidelines to avoid cross-compatibility issues which can affect test results.
  • Question: Where can I buy the Ohaus 30087993 Replaceable pH Electrode in Malta?

    Answer: You can purchase the Ohaus 30087993 Replaceable pH Electrode compatible with the ST20 pen meter from Ubuy in Malta.
