It has built-in simple, convenient, practical connection and long life (up to 1 year), which makes it very suitable for long term online monitoring. It has an LED which works as the Power Indicator, a BNC connector, and a PH2.0 sensor interface. To use it, just connect the pH sensor with the BND connector, then plug the PH2.0 interface into the analog input port of any Arduino controller. If programmed, you will get the pH value easily. You may also check Liquid Sensor Selection Guide to get better familiar with our liquid sensor series.\u003cbr\u003e\u003cbr\u003eThis industrial pH electrode is made of sensitive glass membrane with low impedance. It can be used in a variety of PH measurements with fast response and excellent thermal stability. It has good reproducibility, is difficult to hydrolysis, and can eliminate basic alkali error. In 0pH to 14pH range, the output voltage is linear. The reference system which consist of the Ag\/AgCl gel electrolyte salt bridge has a stable half-cell potential and excellent anti-pollution performance. The ring PTFE membrane is not easy to be clogged, so the electrode is suitable for long-term online detection.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003e\u003cspan style=\"color: #ff0000;\"\u003eAttention：\u003c\/span\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003cstrong\u003eNote: \u003c\/strong\u003eAfter you received your package! You may found some white particles on the protection foam which is the KCl crystallization from the cap. Please don't worry about the crystallization in the packing box, that's normal. Actually, since the transportation restriction on liquid, we have poured out the KCL3N solution in the cap, the slight crystallization in the packing box should be leaked since the remnant. Anyway, once you received the probe, you should store it in the KCL3N solution, you cannot leave it in dry circumstance.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eGood News\u003c\/strong\u003e: Gravity: Analog pH Sensor \/ Meter Pro Kit V2 is available now.
