- 廣泛用於化學工業，製藥工業，染料工業和科學研究
- 支持Arduino和Rasberry Pi
- 體積小巧，易於部署且具有成本效益
- 分辨率：最高 ±0.15PH（STP）
- 探頭可更換
規格
- 工作電壓：3.3V / 5伏
- 範圍：0-14PH
- 解析度：±0.15PH（STP）
- 響應時間：＜1分鐘

注意事項
- 在測量之前，必須使用已知PH值的標準緩衝溶液校準電極。為了獲得更準確的結果，已知的PH值應該是可靠的，並且更接近所測值。
- 測量完成後，應戴上電極保護套。應在保護套中放入少量3.3mol / L氯化鉀溶液，以保持電極燈泡濕潤。
- 電極的前端必須保持清潔乾燥，以絕對防止輸出兩端短路，否則會導致測量結果不准確或無效。
- 長期使用電極後，如果發現梯度略有誤差，可以將電極的下端浸入4％HF（氫氟酸）中3-5秒，然後用蒸餾水洗滌，然後浸泡在氯化鉀溶液中使其變新。
- 本產品未通過 RoHS 認證。
- 本產品不應長時間浸泡在任何溶液中

Description
Are you trying to find an easy to use and cost-effect PH sensor/meter? Do you want to use a PH sensor/meter with Arduino or Raspberry Pi? Well, this new Grove – PH Sensor will meet all your needs. The PH sensor measures the hydrogen-ion activity in water-based solutions, we usually use it to measure the PH of a liquid. It is widely used in the chemical industry, the pharmaceutical industry, the dye industry, and scientific research where acidity and alkalinity testing is required. The drive board in this kit support both 3.3V and 5V system. And with the stander BNC probe interface and Grove connector, it is very convenient to work with Arduino and Raspberry Pi.

Cautions
- Before being measured, the electrode must be calibrated with a standard buffer solution of known PH value. In order to obtain more accurate results, the known PH value should be reliable, and closer to the measured one.
- When the measurement is completed, the electrode protective sleeve should be put on. A small amount of 3.3mol / L potassium chloride solution should be placed in the protective sleeve to keep the electrode bulb wet.
- The leading end of the electrode must be kept clean and dry to absolutely prevent short circuits at both ends of the output, otherwise it will lead to inaccurate or invalid measurement results.
- After long-term use of the electrode, if you find that the gradient is slightly inaccurate, you can soak the lower end of the electrode in 4% HF (hydrofluoric acid) for 3-5 seconds, wash it with distilled water, and then soak in potassium chloride solution to make it new.
