Our general-purpose pH Sensor can be used across disciplines, including chemistry, biology, middle school science, and environmental science.
Use the pH Sensor just as you would a traditional pH meter with the additional advantages of automated data collection, graphing, and data analysis. Typical activities using our pH sensor include:
- Acid-base titrations
- Studies of household acids and bases
- Monitoring pH change during chemical reactions or in an aquarium as a result of photosynthesis
- Investigations of acid rain and buffering
- Analysis of water quality in streams and lakes
If you are studying Tris buffers or semisolids such a soil slurry, consider the Vernier Tris-Compatible Flat pH Sensor.

Use the Tris-Compatible Flat pH Sensor to measure the pH of a solution or semisolid, such as food or soil.
The Tris-Compatible Flat pH Sensor is a highly versatile sensor. Because the glass membrane is flat instead of a bulb, it is more durable, easier to clean, and allows for flat surface measurements or smaller sample sizes. It features a sealed, gel-filled, double-junction electrode, making it compatible with Tris buffers and solutions containing proteins or sulfides. The flat glass shape also makes it useful for measuring the pH of semisolids such as food or soil slurries.
