Has a wide measurement range of 0 to 14 pH. Has a resolution of 0.01 ph. For use with PASPORT Interfaces.
See the Buying Guide for this item's required, recommended, and additional accessories.
Product Summary
The PASPORT pH Sensor measures the hydronium ion concentration in a solution and reports it as a pH value. This sensor is well-suited for a variety of activities where testing or monitoring acidity is important.
Resolution is a very important feature of pH meters, but high resolution is useless if the noise is high. This sensor's digital technology provides 0.01 pH resolution and low noise to produce more accurate, stable data. It is useful for measuring both sublte and large changes in pH.
Applications
- Titrate an acid into a base
- Investigate the chemistry of buffers
- Monitor water quality

pH Sensors & Probes
A pH sensor is a type of probe used to measure the pH of solutions in chemistry, biology, and other science applications. pH probes are often used to determine the basicity or acidity of an aqueous solution.
Titration
A titration is a chemical analysis in which a researcher determines the concentration of a chemical solution (analyte or titrand) by adding a measured volume of standard solution (titrant) until the produced reaction reaches the equivalence point.
