Feature:
1. The waterproof and dustproof grade can reach IP68, ensuring the components to run normally for a long time.
2. PH value within 3-9PH can be measured with high accuracy up to ±0.3PH.
3. High density resin is used for high temperature vacuum filling between the probe and the body, which can prevent moisture from entering the body interior and has good sealing performance.
4. Suitable for agricultural cultivation, industrial production, environmental monitoring, animal husbandry and sewage treatment.
5. Easy to operate and portable to carry around. High accuracy and quick response, providing fast, accurate and reliable reading data.

Usage:
1. Surface measurement method: select a suitable measurement site, avoid stones, ensure that the steel needle will not touch hard objects, cut the surface layer according to the required measurement depth, maintain the original tightness of the soil below, hold the sensor vertically inserted into the soil, do not move from side to side when inserting, it is recommended to conduct multiple measurements to calculate the average value.
2. Buried measurement method: dig a pit with a diameter of >20cm vertically, insert the steel needle of the sensor into the wall of the pit horizontally at the established depth, fill the pit tightly, and after stabilizing for a period of time, measure and record for several days, months or even longer time.
