Gravity: Analog Spear Tip pH Sensor / Meter Kit (for Soil and Food Applications)

This amazing spear tip pH sensor/meter kit is a game - changer for measuring pH values in semisolid materials. It's perfect for testing the pH of wet soil and a wide range of foods. The soil's pH is crucial for plant growth, as different plants thrive in different pH conditions. For foods like fruits, meats, and vegetables, pH is a key quality indicator. For example, by measuring meat's pH, you can quickly tell if it's fresh. The pH probe in this kit has a sharp - tipped stainless - steel spear - like protection shield. This allows it to be directly stabbed into soft semisolid materials such as wet soil or foods, something a common pH probe can't do without getting damaged. It's Arduino compatible, making it super easy to use. You can quickly build a pH meter to directly measure the pH of soil or foods. Attention: Don't measure hard solid samples or semisolid samples with sharp particles. Keep the probe plug, signal transmitter board (especially the BNC connector) clean and dry. This pH probe is a lab electrode, so don't immerse it in the measured object for a long time. After use, clean the probe carefully. Check that the measured objects won't harm the probe's black ABS shell, glass component, and silicone rubber material. It's not suitable for oily samples, high - viscosity samples, samples with many fine particles, or non - aqueous titration. Be careful as the stainless - steel spear tip is sharp. Features: The product uses a pH probe with a spear tip shell, enabling direct measurement of pH in semisolid materials.

Using this pH sensor/meter kit is easy. First, if you're using it with an Arduino, connect it as per the Arduino pH sensor connection guide. Then, for measuring the pH of wet soil or foods, simply take the probe and gently stab it into the semisolid material. But remember, don't use it on hard solid samples or those with sharp particles, as it can damage the probe. Keep the plug of the probe and the signal transmitter board clean and dry, especially the BNC connector. After you're done measuring, don't leave the probe immersed in the object for a long time because it's a laboratory electrode. Clean the probe carefully after each use. Before testing an object, make sure it won't harm the black ABS shell, glass component, and silicone rubber of the probe. Avoid using it for oily samples, samples with high viscosity, or those with many fine particles, and it's not for non - aqueous titration. Also, be careful when handling the probe as the stainless - steel spear tip is sharp.
