As an upgraded version of pH meter V1, this product greatly improves the precision and user experience. The onboard voltage regulator chip supports the wide voltage supply of 3.3~5.5V, which is compatible with 5V and 3.3V main control board. The output signal filtered by hardware has low jitter. The software library adopts the two-point calibration method, and can automatically identify two standard buffer solutions (4.0 and 7.0), so simple and convenient. Liquid Sensor Selection Guide With this product, the main control board (such as Arduino), and the software library, you can quickly build the pH meter, plug, and play, no welding. DFRobot provides a variety of water quality sensor products, uniform size, and interface, not only meet the needs of various water quality testing but also suitable for the DIY of multi-parameter water quality tester. The pH is a value that measures the acidity or alkalinity of the solution. It is also called the hydrogen ion concentration index. The DH is a scale of hydrogen ion activity in solution. The pH has a wide range of uses in medicine, chemistry, and agriculture. Usually, the pH is a number between 0 to 14. Under the thermodynamic standard conditions, pH=/, which means the solution is neutral; pH</, which means the solution is acidic; pH>7, which means the solution is alkaline. ei ANALOG IN 3] m = aa a a loiane sis Vl A : fer as Ca Tb, 6: TOIT O = i = SS XN S Calibrating an Analog pH Sensor (with Linear Algebra) GS) Calibrating an ApalogypH Sensor (with Linear Alg...

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 itis damp, it needs to be dried. 2. [he signal conversion board cannot be directly placed on a wet or semiconductor surface, otherwise, it will affect the input impedance, resulting in the inaccurate measurement. It is recommended to use the nylon pillar to fix the signal conversion board, allow a certain distance between the signal conversion board and the surface. 3. The sensitive glass bubble in the head of the pH probe should avoid touching with the hard material. Any damage or scratches will cause the electrode to fail. 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.

El producto llego bien empacado y muy rapido. Tuvieron que tirar las soluciones amortigquadoras antes de enviarmelas para evitar problemas en la aduana de Mxico, pero el vendedor me pidio la autorizacion antes de enviar el producto. Fueron muy responsables. El producto funciona muy bien eKkek&kk Ramss Ismael. 07/07/2020 FAQ SUS OMS TAI Gravity: Analog pH Sensor/Meter Kit V2 SKU:SEN0O161-V2 Brand:DFRobot Reward Points: 395 In Stock Categories: Topic: * Model: pH Meter pH Meter V2 pH Meter Pro pH Meter Pro V2 Spear Tip pH Meter pH Probe Pro Quantity: 1 Sign up for exclusive offers!
