Analog Spear Tip pH Sensor / Meter Kit (measures pH of soil and food)
Soil pH is an important parameter that affects the growth of plants. Different plants have different soil pH values for growth. Different foods, such as fruits and meats, have different pH values. The pH of food is also an important parameter, such as judging the quality of meat by detecting the pH of meat. For semi-solid materials such as soil and food, ordinary pH electrodes cannot be directly measured, otherwise the electrodes may be abnormal or even damaged. To this end, we have introduced this cone pH meter. The pH electrode of this product is equipped with a stainless steel needle-punched sheath, which can directly pierce semi-solid materials, so it can conveniently measure the pH value of wet soil, food (such as meat, fruits) and other materials. of.
This product is compatible with Arduino, plug and play, simple and convenient, can quickly DIY a pH detector, directly measure the pH value of soil or food.
Technical specifications
Conical pH electrode
Signal transfer board
![]() ![]() pH electrode characteristics The output signal of the pH electrode is a millivolt-level voltage, which has a corresponding relationship with the pH value. At 25 ° C, the relationship between the ideal output voltage and pH is as follows:
![]() Assembling a conical pH electrode
Before measuring semi-solid materials, the pH electrode must be fitted with a stainless steel needle-punched sheath. If calibration is performed in standard buffer, the stainless steel needling sheath may not be installed first. After the calibration is completed, install it again.
First remove the protective liquid bottle and cap of the pH electrode, then unscrew and remove the retaining ring. Then carefully put the stainless steel needle guard into the electrode head, then install and tighten the retaining ring. For specific installation operations, please refer to the figure below.
