INTRODUCTION

Gravity: Analog Spear Tip pH Sensor / Meter Kit Overview

This Gravity: Analog Spear Tip pH Sensor / Meter Kit can directly stab into semisolid material to measure the pH value. It can be used to measure the pH value of wet soil and various foods.

The pH value of the soil is an important factor affecting the growth of plants. Suitable pH values for different plants differ from each other. The pH value of foods, such as fruit, meat, and vegetable are also an important indicator of their quality. For example, by measuring the pH value of meat, we can determine whether the meat we bought is fresh or not.

The pH probe of this kit is attached with a spear-like protection shield made of stainless steel with a sharp tip. It can be directly stabbed into the soft semisolid material to measure the pH value, such as wet soil or foods. But this can not be done with a common pH probe, or it will be damaged.

This kit is Arduino compatible and easy to use. It helps you to quickly build a pH meter to measure the pH value of soil or foods directly.

Attention:

*It is forbidden to measure hard solid samples and semisolid samples containing sharp particles.

*Please keep the plug of the probe, signal transmitter board (especially the BNC connector) clean and dry.

*This pH probe is a laboratory electrode, which is not suitable for prolonged online testing. Therefore, do not immerse the electrode in the measured object for a long time.

*After using the pH probe, please clean it carefully.
