Description :

• DFRobot Gravity: Analog pH meter pro V2 is specifically designed to measure the pH of solutions
• Upgraded version of pH meter pro V1, improves precision and user experience
• Onboard voltage regulator chip supports 3.3~5.5V wide voltage supply, compatible with 5V and 3.3V main control boards
• Output signal filtered by hardware has low jitter
• Software library adopts two-point calibration method and can automatically identify two standard buffer solutions (4.0 and 7.0)
• Uses industry electrode with built-in simple, convenient, practical connection and long life
• Suitable for online monitoring
• Uses a sensitive glass membrane electrode with low impedance, fast response, and good thermal stability
• Reference system has stable half-cell potential and excellent anti-pollution performance
• Ring PTFE membrane is not easy to be clogged, suitable for long-term online detection
• Can quickly build pH meter with main control board and software library, no welding required
• Suitable for DIY multi-parameter water quality tester
• pH is a value that measures acidity or alkalinity of a solution, with a range of uses in medicine, chemistry, and agriculture
• pH is a scale of hydrogen ion activity in a solution, with a range of 0-14. Neutral solutions have a pH of 7, acidic solutions have a pH below 7, and
• alkaline solutions have a pH above 7.
• BNC connector and signal conversion board must be kept dry and clean to avoid affecting input impedance
• Signal conversion board cannot be placed on wet or semiconductor surface
• Sensitive glass bubble in the head of the pH probe should avoid touching hard material
• Disconnect pH probe from signal conversion board after measurement
• Bottle cap of probe contains protective liquid, any leakage will not affect life and accuracy of probe.
