Industrial-Grade Performance 工業級性能
Designed for continuous operation, this sensor supports 7/24-hour monitoring with a lifespan exceeding 4380 hours, ensuring consistent performance in demanding environments.
該感測器專為連續運作而設計，支援7/24 小時監控，使用壽命超過4380 小時，確保在嚴苛環境下保持一致的性能。
Exceptional Accuracy 卓越的準確性
Achieving a measurement accuracy of ±0.1 pH at 25°C, the device employs a two-point calibration method, enabling users to effortlessly calibrate using standard buffer solutions (4.0 and 7.0). This precision is vital for applications where accurate pH levels are critical.
該設備在 25°C 下實現±0.1 pH 的測量精度，採用兩點校準方法，使用戶能夠使用標準緩衝溶液（4.0 和 7.0）輕鬆校準。這種精確度對於精確 pH 值至關重要的應用至關重要。
Robust Design and Compatibility 穩健的設定和相容性
The sensor operates within a wide voltage range of 3.3 to 5.5V, making it compatible with various main control boards like Arduino and LattePanda. The plug-and-play design, featuring a BNC connector, simplifies setup and reduces installation time.
此感測器工作電壓範圍較寬，為3.3V至5.5V，相容於Arduino、LattePanda等多種主控板。即插即用設計採用 BNC 連接器，簡化了設定並縮短了安裝時間。

Attention 注意力：
1. The BNC connector and the signal conversion board must be kept dry and clean, otherwise, it will affect the input impedance, resulting in an inaccurate measurement. If it is damp, it needs to be dried.
BNC連接器和訊號轉換板必須保持乾燥、清潔，否則會影響輸入阻抗，導致測量不準確。如果受潮，則需要乾燥。
2. The signal conversion board cannot be directly placed on a wet or semiconductor surface, otherwise, it will affect the input impedance, resulting in an inaccurate measurement. It is recommended to use the nylon pillar to fix the signal conversion board, and allow a certain distance between the signal conversion board and the surface.
訊號轉換板不能直接放置在潮濕或半導體表面上，否則會影響輸入阻抗，導致測量不準確。建議使用尼龍柱固定訊號轉換板，並讓訊號轉換板與表面留有一定的距離。
3. The sensitive glass bubble in the head of the pH probe should avoid touching the hard material. Any damage or scratches will cause the electrode to fail.
pH探頭頭部的敏感玻璃泡應避免接觸硬質物質。任何損壞或刮傷都會導致電極失效。
4. After completing the measurement, disconnect the pH probe from the signal conversion board. The pH probe should not be connected to the signal conversion board without the power supply for a long time.
測量完成後，斷開pH探頭與訊號轉換板的連接。 pH探頭不宜在沒有電源的情況下長時間連接到訊號轉換板。
5. The bottle cap of the probe contains protective liquid (3.3mol/L KCL). Even if the bottle cap is screwed tightly, some protective liquid may still leak around the bottle cap, forming white crystals. But as long as there is still protective liquid in the bottle cap, it will not affect the life and accuracy of the probe. So please use it with confidence. It is recommended that the white crystals be poured back into the protective liquid in the bottle cap.
探頭瓶蓋內裝有保護液（3.3mol/L KCL）。即使瓶蓋擰緊，一些保護液仍可能從瓶蓋周圍洩漏，形成白色晶體。但只要瓶蓋內還有保護液，就不會影響探頭的壽命和精準度。所以請放心使用。建議將白色晶體倒回瓶蓋內的保護液中。
