Product Description

Description:

This is a professional Arduino pH Sensor Meter Kit with an industrial electrode. 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.

This 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.

Attention：

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.

Note: After 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.

Description:

The Gravity: Analog pH Sensor / Meter Pro Kit V2 stands out for its industrial-grade durability, exceptional accuracy, and user-friendly design. It is an essential tool for anyone involved in precise water quality monitoring and management.

Industrial-Grade Performance

Designed for continuous operation, this sensor supports 7/24-hour monitoring with a lifespan exceeding 4380 hours, ensuring consistent performance in demanding environments.

Exceptional Accuracy

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.

Robust Design and Compatibility

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.

Attention：

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.

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.

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.

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.

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.
