pH Sensor

$88.00

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

ORDER CODE: PH-BTA Categories ,

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.

Specifications

  • Type: Sealed, gel-filled, epoxy body, Ag/AgCl
  • Shaft Diameter: 12 mm OD
  • Response time: 90% of final reading in 1 second
  • Temperature range: 5 to 80°C
  • Range: pH 0–14
  • Accuracy: +/- 0.2 pH units
  • Isopotential pH: pH 7 (point at which temperature has no effect)
