Gravity: 錐形模擬 PH值 感測器 傳感器 (測量土壤與食物的PH值)

商品說明

這是一款錐形 pH値 感測器，可直接刺入半固體物質測量 pH值，可應用於濕潤土壤、各種食物的 pH值測量。

土壤的 pH值 是一個重要的參數，影響著植物的生長。不同的植物，適宜生長的土壤pH值是不一樣的。不同的食物，如水果、肉類等，它們的pH值也是不同的。食物的pH值也是一個重要的參數，如通過對肉類pH值的檢測，來判斷肉類的質量。

對於土壤、食物這類半固體物質，普通pH電極不可直接測量，不然容易導致電極異常甚至損壞。為此，我們推出了這款錐形pH計。該產品的pH電極帶有不銹鋼針刺護套，可直接刺入半固體物質，因此可方便的測量濕潤土壤、食物（如肉類、水果）等物質的pH值，這是普通pH電極不能達到的。

本款 PH值 感測器 兼容 Arduino，即插即用，簡單方便，可快速DIY一個pH檢測儀，直接測量土壤或食物的pH值。

注意：

1.嚴禁用於測量堅硬的固體樣品、含有尖銳顆粒的半固體樣品。

2.請始終保持電極插頭、信號轉接板（特別是BNC接口座）的清潔及乾燥。

3.本電極為實驗室電極，不適用於長時間的在線測試，因此請勿將電極長時間浸泡於被測物內。

4.電極使用完畢，請認真對電極進行清洗工作。

5.本產品接觸被測物的部件有黑色ABS外殼、玻璃組件和矽橡膠材料，測試被測物之前需確認被測物對這些材料沒有傷害。

6.不適合測量：油性樣品、粘度較大的樣品、含較多細微顆粒的樣品。

7.不適用於非水滴定。

8.不銹鋼護套的頭部比較尖銳，使用時請注意安全。

技術補充（英文）

以下為原廠英文技術說明，提供使用者參考。

This spear tip pH sensor/meter kit can directly stab into semisolid material to measure the pH value. It can be used to measure 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 value 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 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.
*The components of this probe which touch the measured objects have a black ABS shell, a glass component and a silicone rubber material. Before testing the object, it is necessary to confirm that the measured objects are not harmful to these materials.
*Not suitable for measurement: oily samples, samples with higher viscosity, samples with more fine particles.
*Not suitable for non-aqueous titration.
*The head of the stainless steel spear tip is sharp. Please pay attention to safety when using it.
