Our general-purpose pH Sensor can be used across disciplines, including chemistry, biology, middle school science, and environmental science.

ORDER CODE: PH-BTA Categories ,

Due to recent changes in U.S. trade policy, new tariffs are being implemented that impact our products. This means a surcharge of 5% will be applied to orders received starting May 12th, with the exception of software and books. Learn more.

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.
