Gravity: Analog pH Sensor/Meter Kit V2

DFRobot Gravity: The V2 analogue pH meter is specifically designed to measure the pH of the solution and reflect the acidity or alkalinity. The DFRobot ph sensor is commonly used in various applications such as aquaponics, aquaculture and environmental water testing.

The pH is a value that measures acidity or alkalinity.

As an upgraded version of the V1 meter, it greatly improves accuracy and user experience. The on-board 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 hardware filtered output signal has low jitter. The software library adopts two-point calibration method, and can automatically identify two standard buffer solutions (4.0 and 7.0), so simple and convenient.

Attention :

  • The BNC connector and signal conversion board should be kept dry and clean, otherwise it will affect the input impedance, resulting in inaccurate measurement. If it is wet, it needs to be dried.
  • The signal conversion board cannot be placed directly on a wet or semi-conducting surface, otherwise it will affect the input impedance, resulting in inaccurate measurement. It is recommended to use the nylon pillar to fix the signal conversion board, leave a certain distance between the signal conversion board and the surface.
  • The sensitive glass bubble in the head of the pH probe should avoid contact with the hard material. Any damage or scratches will cause the electrode to fail.
  • After completing the measurement, disconnect the pH probe from the signal conversion board. The probe of the analogue pH sensor must not be connected to the signal conversion board without the power supply for a long time.
  • Under standard thermodynamic conditions, pH=7, means the solution is neutral; pH<7, means the solution is acidic; pH>7, means the solution is alkaline.
